## Description
LC Smart Media Redirect & Cleaner keeps your Media Library lean without ever breaking
a front-end
image. It intelligently redirects missing/mismatched thumbnail-size
requests to the closest available size instead of letting them 404 or silently regenerate
on every request, scans for orphaned metadata and unused files, and gives you a
safe, reviewable prune tool.
Features:
* **Adaptive CPU Load Throttling & Background Engine** — Real-time server CPU load
monitoring (`get_server_cpu_load()`) with dynamic batch pacing, cooling backoffs,
and safe execution.
* **Smart Core Web Vitals (LCP) Booster & Hero Preload Engine** — Automatically
detects hero images, strips `loading="lazy"`, injects `fetchpriority="high"`
and `decoding="async"`, and outputs high-priority `` in `
`.
* **Master Original Image Dimension Cap & Auto-Downscaler** — Resizes oversized
raw master camera/iPhone uploads in place (e.g. capped at 2560px or 2048px) to
eliminate hosting bloat.
* **Native WP-CLI Command Suite** — Comprehensive terminal management via `wp smrc
stats`, `wp smrc regen`, `wp smrc prune`, and `wp smrc redirect`.
* **Interactive Visual Quality & Savings Comparison Modal** — Apple-style split
comparison slider with real-time file size & % savings calculations.
* **Smart Size Redirect** — serves the closest matching registered image size instead
of a
broken or oversized fallback.
* **Metadata Orphan Scanner** — manual, batched scan for attachment metadata pointing
at files
that no longer exist.
* **Prune Tool** — review orphaned files before removing them; nothing is deleted
blindly.
* **Future Generation Manager & custom image size management.**
* **Background thumbnail regeneration** via WP-Cron, batched to avoid timeouts.
* **App-like dashboard** with single-site storage stats, export/import configuration.
* **Staging-to-Live Production Preset Sync** — export complete configurations (
core dimensions, size selections, Smart Size Redirect rules, and Pro engines)
for seamless local-to-live migration.
Need automated (no-click) background maintenance, AVIF/WebP multi-format delivery,
auto-compression, or
multisite/CDN-aware storage analysis? See **LC Smart Media
Redirect & Cleaner Pro**, the licensed add-on.
This plugin is the direct successor to “Batch Image Cleaner” (v1.9.28 and earlier);
Standard
free features and stored settings remain fully compatible.
### Current Active Pipeline Status
* **Standard lifecycle (v1.9.33, audited August 8, 2026):** ✅ Bootstrap order,
migration, activation/deactivation, cron ownership, uninstall cleanup, and legacy
URL handling were traced end to end. Three defects were fixed: query-string false-
positive 410 responses, stale deactivation orphan-scan state, and retained dynamic
prune sessions after uninstall.
* **Future-upload size generation & Image Size Manager (v1.9.56, audited August
19, 2026):** ✅ `smrc_get_registered_sizes()` updated to read unfiltered registrations
directly from `Smrc_Core::get_image_sizes()`. Custom registration, override ordering,
disabled-size filtering, minimum-longest-side behavior, duplicate-size deduplication,
and post-upload metadata were traced end to end. All 26 registered sizes (Core,
Theme, WooCommerce, Custom) reliably render on the Image Sizes grid regardless
of active upload generation state.
* **Dashboard configuration controls (v1.9.35, audited August 8, 2026):** ✅ Rendered
controls, action bindings, nonces/capabilities, option persistence, import/export,
and completion feedback were traced end to end. Two UI defects were fixed: numeric
settings now acknowledge or safely roll back failures, and the unused scan-subfolder
selector was removed.
* **Manual thumbnail regeneration (v1.9.36, audited August 8, 2026):** ✅ Selected-
size persistence, reset/resume/run loop, locks, attachment processing, file/metadata
writes, errors, stop, and recovery controls were traced end to end. Two defects
were fixed: Stop no longer releases the lock during an active batch, and the
live error total includes every batch error.
* **Background thumbnail regeneration (v1.9.37, audited August 8, 2026):** ✅ AJAX
start/status/cancel, cron scheduling, run state, locks, batch processing, completion,
stale recovery, and UI feedback were traced end to end. Four concurrency/recovery
defects were fixed: duplicate starts and callbacks are blocked, cancellation
cannot be overwritten by an in-flight batch, and malformed running state recovers
safely.
* **Background orphan scanner (v1.9.38, audited August 8, 2026):** ✅ Start/status/
cancel/clear AJAX, WP-Cron scheduling, persistent offsets/results, filesystem
and metadata phases, result caps, cancellation, stale recovery, and UI polling
were traced end to end. Four concurrency/recovery defects were fixed: duplicate
starts and cron callbacks are blocked, cancellation cannot be overwritten by
in-flight work, malformed state recovers to idle, and structured UI failures
are handled correctly.
* **Cleanup and prune execution (v1.9.39, audited August 8, 2026):** ✅ Analysis
safety set, prune preparation, transient ownership, batched deletion, per-file
path handling, orphan metadata/file deletion, and client completion feedback
were traced end to end. Two safety defects were fixed: every batch revalidates
its reviewed filesystem scope, and the UI only confirms deletion after a successful
server response.
* **Rebrand compatibility (v1.9.40, audited August 8, 2026):** ✅ Standard bootstrap,
class/function identity, shared cron hooks/state, Pro dependency contract, and
exported UI metadata were traced end to end. Runtime and exported metadata now
use the Smart Media name; retained `bic_*` keys are data compatibility identifiers,
not executable class/function names.
* **Active runtime boundary (v1.9.41, audited August 8, 2026):** ✅ Configuration
import validation now accepts only Smart Media exports. The retired Batch Image
Cleaner is not used as a runtime or import dependency; retained `bic_*` values
remain stored-data compatibility only.
* **Deletion and regeneration safety (v1.9.42, audited August 8, 2026):** ✅ Folder
deletion, thumbnail-size deletion, metadata-derived file paths, foreground size
selection, and lifecycle cleanup were rechecked. Four defects were fixed: unsafe
deletion inputs are rejected, failed deletes retain metadata, folder traversal
refuses symlinks/out-of-scope entries, and regeneration processes only active
image sizes.
* **Third-pass deletion revalidation and state hardening (v1.9.44, audited August
8, 2026):** ✅ Orphan deletion (metadata + files), regeneration lock lifecycle,
prune lock recovery, custom-size deletion, size-override read paths, configuration
import validation, and uninstall coverage of lock options and dynamic scan-accumulator
transients.
* **Smart Size Redirect (Standard, v1.9.55, audited August 18, 2026):** ✅ Dynamic
canonical discovery, aspect-ratio/crop-mode compatibility scoring, manual destination
overrides, auto-match reset, and frontend `image_downsize`/srcset behavior were
traced end to end.
* **Fourth-pass deep audit (Standard + Pro, audited August 10, 2026):** ✅ Thumbnail
Regeneration, Future Generation & Custom Sizes, Storage Overview & Config Backup,
Pro License Engine, Pro WebP Pipeline, Pro Auto-Compression Pipeline, Pro Automated
Maintenance, and Pro Multisite & CDN Storage Analysis were thoroughly reviewed
end to end. Validated correctness, state transitions, fail-closed safety checks,
and edge-cases. Found no regressions or new bugs. The fixes applied in previous
passes successfully resolved all prior defects in these pipelines.
## Installation
1. Upload the `lc-smart-media-redirect-cleaner` folder to `/wp-content/plugins/`.
2. Activate the plugin through the **Plugins** menu in WordPress.
3. Access the dashboard from the new **Media Redirect** menu item in your WordPress
admin.
## FAQ
### If AVIF and WebP files are so small, why do we still need thumbnail sizes?
AVIF and WebP solve file compression (bytes per pixel), but thumbnail sizes solve
display resolution, mobile GPU memory decoding, and responsive srcset layout. Even
an ultra-compressed 24-megapixel AVIF takes 96 MB of RAM for a mobile device to
decompress into GPU memory; loading 30 full-res images on a mobile page can cause
browser lag or out-of-memory crashes. Resizing to a thumbnail (e.g. 400×300 px)
in AVIF reduces file size from ~350 KB down to just ~8 KB (a 99.8% reduction!) while
decoding in under 0.5 MB of RAM. LC Smart Media Redirect & Cleaner lets you keep
only the 2-3 essential responsive sizes in AVIF/WebP, and dynamically redirects
any missing legacy requests on the fly with zero 404s.
### How does Smart Size Redirect prevent broken images?
When a theme or plugin requests an image size that you deleted or disabled, Smart
Size Redirect intercepts the request and dynamically serves the closest available
registered size with matching aspect ratio, preventing broken layouts without generating
unnecessary files.

* ENHANCEMENT — Added dimension cap preset pills and LCP toggle in Settings tab.
#### 1.9.57 (August 19, 2026)
* REFACTOR — Modernized all plugin options, transients, cron hooks, and postmeta
to `smrc_*` prefix with automatic zero-data-loss migration on boot (`maybe_migrate_legacy_bic_data()`).
* ENHANCEMENT — Configuration export/import uses clean `smrc_*` keys while seamlessly
supporting legacy import formats.
#### 1.9.56 (August 19, 2026)
* FIX — `smrc_get_registered_sizes()` now uses `Smrc_Core::get_image_sizes()` directly,
ensuring all registered theme, WooCommerce, and custom image sizes appear in
the Image Sizes tab even when disabled from upload generation.
#### 1.9.55 (August 18, 2026) – Pipeline Audit: SSR Algorithmic Grounding & UI Hardening
* FIX — Smart Size Redirect (P2): Added `$ignore_custom_mappings` parameter to `
find_best_redirect_target()` to compute pure algorithmic defaults independently
of active manual overrides, ensuring “Reset Mappings to Auto” always accurately
restores true algorithmic matches.
* ENHANCEMENT — Added `OVERRIDE` badge indicator on SSR dashboard chips whenever
a custom manual destination is active.
* ENHANCEMENT — Automatic clean-up of redundant mappings during save so options
storage remains minimal and dynamic.
* ENHANCEMENT — Dashboard view auto-refreshes seamlessly upon saving SSR destination
modifications.
#### 1.9.54 (August 18, 2026) – Staging-to-Live Production Preset Sync & Filter Extensibility
* FEATURE — Enhanced Configuration Export & Import to bundle WordPress Core Dimensions(`
thumbnail`, `medium`, `large`, crop settings) and Smart Size Redirect rules (`
bic_size_redirect` with exclusions and custom dynamic mappings).
* FEATURE — Added `smrc_export_config_payload` filter and `smrc_import_config_settings`
action hooks, enabling Pro to serialize and restore complete optimization stacks.
* ENHANCEMENT — Updated dashboard UI with dedicated Staging Sync card and updated
export filename format (`smrc-config-YYYY-MM-DD.json`).
#### 1.9.52 (August 18, 2026) – Pipeline Audit Fixes: Smart Size Redirect & Thumbnail Deletion Hardening
* FIX — Smart Size Redirect (P2): `get_size_width_unfiltered()` previously checked
options-table widths for core sizes `1536x1536` and `2048x2048`, where options
do not exist. Removed them from core options lookup so they properly resolve
from `$_wp_additional_image_sizes` (1536px and 2048px) and map to large thumbnails
instead of falling back to full master photos.
* FIX — Batch Deletion Hardening (P4): `delete_all_thumbnails_batch()` now enforces`
realpath`, uploads base-prefix boundary matching, and symlink skipping matching
the security model of `delete_thumbnail_size_files()`.
#### 1.9.51 (August 17, 2026) – Storage Breakdown WebP Metrics, Prune Tool Lifecycle & Admin Notice Alignment
* FIX — Storage breakdown metrics: storage overview calculation (`get_database_statistics`,`
get_folder_statistics`, `scan_stats_batch`) now includes `.webp` companion file
sizes in `total_size` and computes `webp_percentage` accurately. Added dynamic`#
smrc-bar-webp` segment and legend to the Storage Breakdown dashboard card.
* FIX — Prune Tool lifecycle: fully wired `#smrc_prune_run`, `#smrc_prune_cancel`,
batch deletion progress chunks, and scan status UI in admin script and stylesheet.
* FIX — Admin notices: aligned minimum WordPress version requirement notice in `
class-admin-interface.php` from legacy 4.0 to 5.0, matching plugin declarations
and runtime requirements.
* HOUSEKEEPING — Synced Author URI to `https://www.lightandcomposition.com/`.
#### 1.9.50 (August 14, 2026) – Plugin URI Fix
* HOUSEKEEPING — `Plugin URI` now points to the plugin’s Dev Lab page (`/dev/smart-
media-redirect-cleaner/`) instead of the wordpress.org listing.
#### 1.9.49 (August 10, 2026) – Critical bug fixes: delete_thumbnail_size_files & Generation Control
* FIX — `delete_thumbnail_size_files()`: `$uploads_prefix` was undefined inside
this function (only set in the sibling `delete_all_thumbnails_batch()`). Caused
the path-traversal guard to always be empty-string truthy silently skipped every
file “Delete Size” button did nothing. Variable now properly derived from `realpath(
wp_upload_dir()['basedir'])`.
* FIX — Quick Setup “Generation Control” step: marked incomplete even after user
selected ALL sizes because the old condition required `selected_count < total_reg_count`.
New logic: step is done if (a) any disabled sizes, (b) any selected sizes (including
all), or (c) the option was ever explicitly saved in the DB (`get_option` sentinel
check).
#### 1.9.48 (August 10, 2026) – Generation Control Quick Setup evaluation enhancement
* FIX — Generation Control (Step 3) now considers setup complete if unused sizes
are unselected/excluded in Image Sizes tab (`selected_sizes` < registered count)
OR if Uploads creation is disabled (`disabled_sizes` is non-empty).
#### 1.9.47 (August 10, 2026) – Quick Setup progress tracker & layout audit
* NEW — 5-step Quick Setup progress tracker on Overview dashboard (PHP Image Engine,
Smart Size Redirect, Generation Control, Compression & Quality, Safety Shields).
* FIX — Step 3 button target updated to `image-sizes` tab ID for seamless jump
navigation.
* FIX — Added `flex: 0 0 auto` to `.smrc-qs-step` containers to prevent flex shrinkage
and line overlaps across step labels.
* FIX — Added strict `text-decoration: none !important` overrides to eliminate
WordPress core `.is-done` strike-through text styling.
* FIX — 100% complete state now collapses into clean compact banner with expandable
breakdown.
#### 1.9.44 (August 8, 2026) – third-pass deletion revalidation and state hardening
* FIX — orphaned-metadata deletion re-validates every submitted ID at delete time(
must still be an attachment whose original file is missing); a stale or replayed
request can no longer delete a valid attachment.
* FIX — orphaned-file deletion re-checks at delete time that each file is not a
registered attachment or a thumbnail of one, closing the scan-to-delete race
window.
* FIX — a foreground regeneration first batch that loses the per-batch processing-
lock race now releases the run claim and 30-minute lock it just created, instead
of blocking all future foreground and background starts.
* FIX — prune batch locks reclaim automatically after 10 minutes if a batch died
fatally, so an interrupted run no longer blocks its review forever.
* FIX — deleting a custom size no longer crashes when the stored list contains
a malformed entry; malformed entries are dropped safely.
* FIX — size-override filtering guards malformed override entries, preventing a
fatal during upload when option data is poisoned.
* FIX — configuration import now sanitizes disabled-size, selected-size, and size-
override arrays to their exact expected shapes instead of storing arbitrary structures.
* FIX — uninstall now removes prune lock options, folder-stats scan accumulator
transients, and regeneration/scan lock options that could previously survive
removal.
#### 1.9.43 (August 8, 2026) – second-pass prune and regeneration safety
* FIX — prune reviews now resolve the uploads scope and every candidate to canonical,
non-symlinked paths; a supplied subfolder must be a real child of uploads.
* FIX — prune state is owned by the administrator who prepared it and each review
token has an atomic deletion-batch lock, preventing concurrent requests from
losing state or double-processing files.
* FIX — cleanup results now distinguish deleted and safely skipped candidates,
while protected-file totals count unique canonical attachment files.
* FIX — foreground and background thumbnail regeneration share atomic start and
batch locks, preventing simultaneous runs from changing the same attachment state.
#### 1.9.42 (August 8, 2026) – deletion and regeneration safety audit
* FIX — thumbnail-size deletion now accepts only currently registered sizes, rejects
unsafe metadata-derived paths, and retains metadata when a physical delete fails.
* FIX — whole-folder deletion now refuses symlinked or out-of-scope entries and
returns a failure instead of claiming success after an incomplete delete.
* FIX — foreground regeneration filters submitted sizes to current WordPress registrations
before it removes old derivatives, and uninstall now clears its activation redirect
transient.
* FIX — aligned the WordPress plugin header with the current Standard runtime version.
#### 1.9.41 (August 8, 2026) – active runtime boundary audit
* FIX — configuration imports now accept only LC Smart Media Redirect & Cleaner
exports. The completely deactivated Batch Image Cleaner is no longer treated
as an executable or import dependency; retained `bic_*` keys remain available
only as existing stored-data compatibility identifiers.
#### 1.9.40 (August 8, 2026) – rebrand compatibility audit
* FIX — executable runtime identity and exported error-log metadata now use the
LC Smart Media Redirect & Cleaner name.
* NOTE — the prior Batch Image Cleaner plugin is deactivated and is not part of
the active runtime. Retained `bic_*` settings, metadata, and cron keys belong
to LC Smart Media Redirect & Cleaner’s existing data contract and are intentionally
not executable class or function names.
#### 1.9.39 (August 8, 2026) – cleanup and prune audit
* FIX — every prune deletion batch now resolves and verifies each stored path against
the exact uploads scope reviewed during preparation, so stale or corrupted cleanup
state cannot delete outside that approved folder.
* FIX — orphan metadata/file deletion now checks JSON success and network failures
before reloading, rather than falsely displaying a successful completion after
a rejected request.
#### 1.9.38 (August 8, 2026) – background orphan scanner audit
* FIX — a running background scan can no longer be overwritten by a second Start
request, and an atomic short-lived cron lock prevents overlapping batches from
racing over shared offsets and results.
* FIX — cancellation or replacement invalidates the active run; an in-flight callback
can finish its current read but cannot publish results, mark the scan complete,
or schedule another batch afterward.
* FIX — missing, malformed, or abandoned run metadata now recovers to idle instead
of leaving the scanner permanently stuck; result arrays are normalized before
status counts are returned.
* FIX — start and cancel failures in the dashboard now display structured server
messages and do not report cancellation as successful when the server rejected
it.
#### 1.9.37 (August 8, 2026) – background thumbnail regeneration audit
* FIX — a running background job can no longer be overwritten by another Start
request, and an atomic cron-batch lock prevents duplicate callbacks from regenerating
the same attachments concurrently.
* FIX — Cancel now invalidates the active run so an in-flight batch cannot revive
or complete it afterward; malformed running state now recovers to idle instead
of remaining stuck forever.
* FIX — background start/cancel errors now show the server’s actual message rather
than an object placeholder or a false successful cancellation state.
#### 1.9.56 (August 19, 2026)
* FIX — `smrc_get_registered_sizes()` now uses `Smrc_Core::get_image_sizes()` directly,
ensuring all registered theme, WooCommerce, and custom image sizes appear in
the Image Sizes tab even when disabled from upload generation.
#### 1.9.65 (August 26, 2026)
* SECURITY & STANDARDS — Updated plugin text domain to `lc-smart-media-redirect-
cleaner` across all PHP files, templates, and translation calls per WordPress.
org Directory slug alignment.
* SECURITY — Hardened input unslashing and strict sanitization across all AJAX
nonce verification routines (`sanitize_text_field( wp_unslash( $_POST['nonce']))`).
* SECURITY — Sanitized request URI checking in core initialization (`esc_url_raw(
wp_unslash( $_SERVER['REQUEST_URI'] ) )`).
* SECURITY — Comprehensive late-escaping audit across all admin views, memory/system
limits, progress bars, and dynamically calculated attributes.
#### 1.9.55 (August 18, 2026)
* FIX — Smart Size Redirect dynamically discovers unfiltered registered sizes and
canonical targets.
#### 1.9.34 (August 8, 2026) – future-upload pipeline audit
* FIX — duplicate-size alias metadata is now scoped to the attachment WordPress
is generating, preventing alias mappings from one upload from leaking into another
image handled in the same request.
* FIX — custom image-size edits now reject duplicate custom names and names already
owned by core, theme, or another plugin instead of creating ambiguous registrations.
#### 1.9.33 (August 8, 2026) – lifecycle pipeline audit
* FIX — legacy-media 410 handling now inspects the request path only, so an unrelated
page whose query string contains an old asset URL is never incorrectly terminated.
* FIX — deactivation now clears the orphan-scan file-list cache, and uninstall
removes dynamic, incomplete prune-run transient state as well as fixed plugin
state.
* FIX — the WordPress minimum-version declaration and activation check are aligned
at 5.0.
#### 1.9.32 (August 6, 2026)
* FIX — Smart Size Redirect now preserves a URL supplied by an earlier `image_downsize`
filter when SMRC has nothing to redirect. This keeps CDN/offload/image-optimization
integrations compatible instead of overwriting their valid result with `false`.
* FIX — the per-request redirect marker is now consumed after its matching srcset
calculation, preventing one redirected image from causing a later unrelated image
srcset to lose its original source.
#### 1.9.31 (August 6, 2026)
* FIX — complete the Standard/Pro dashboard contract audit: corrected renamed UI
hooks, made the background scanner status element unique, and removed obsolete
legacy dashboard assets so controls cannot silently bind to the wrong interface.
* FIX — Storage Overview Refresh now listens to the Smart Media control and reliably
starts its batched scan.
#### 1.0.0 (August 6, 2026) – rebrand/split from Batch Image Cleaner
* First release under the new name. Rebranded from `batch-image-cleaner` (formerly
reachable only
from the WordPress Tools submenu) into its own top-level admin
menu item, redesigned with the shared sidebar + click-to-show-tabs dashboard
used across this plugin suite.
* WebP conversion, auto-compress, and the “Pending Optimization” panel moved to
the new licensed
Pro add-on. All free Standard features and their underlying
option/meta/cron keys are unchanged from Batch Image Cleaner v1.9.28.
