Incod Image Dimension Manager is an original plugin developed, owned and maintained by inCOD (ideagrafica). “Incod” is the author’s own brand: the plugin has no affiliation with, endorsement from, or connection to any other company or project of a similar name. #### Key features * Three resize modes: **Letterbox / Canvas**, **Hard Crop** with a focal point and **Proportional Scale**. * **Customizable HEX fill canvas** (color picker) or **transparent** (PNG/WebP), always centered. * **Dynamic detection of all public Custom Post Types**, WooCommerce included, with multiple selection. * **Auto-resize on upload**: new images are fitted automatically when uploaded. * **Asynchronous Bulk Resize** via AJAX: configurable batches, progress bar, percentage, counters, elapsed time and remaining-time estimate. * **Timeout protection**: time budget per request, adaptive throttle between batches and a mutual-exclusion lock: the server is never saturated. * **Pause**, **Resume** and **Cancel** at any moment, with no limit on the number of images. * **Optional backup of the originals** with batched, progressive restore. * **Imagick** engine with automatic **GD** fallback through `wp_get_image_editor()`. * **Complete security**: capabilities, nonces, sanitization and escaping on every input and output. * **Translatable**: text domain `incod-image-dimension-manager` and a `.pot` file in the `/languages` folder. #### Resize modes * **Letterbox / Canvas Padding** — fits the image inside the target dimensions without cropping and fills the empty space with a customizable (HEX color picker) or transparent canvas (PNG and WebP), with automatic centering. * **Hard Crop** — crops the image to fill the target dimensions completely, with a selectable focal point (Center, Top, Bottom, Left, Right). * **Proportional Scale** — scales the image proportionally without adding a canvas and without destructive cropping. * Option to **prevent upscaling** of images smaller than the target. * **JPEG quality** configurable from 1 to 100. * Images that **already match** the target are skipped automatically, without rewriting the file. #### Custom Post Types * Dynamic detection of every registered public Custom Post Type (WooCommerce Products, posts, pages, portfolios, custom CPTs). * Multiple selection through checkboxes in the settings panel. * Support for Featured Images, child attachments, WooCommerce product galleries(` _product_image_gallery`) and product variation images. * Explicit choice between the **whole Media Library** and **only the images used by the selected post types**. #### Automation and bulk processing * **Auto-resize on upload**: new images are resized automatically when uploaded( hook `wp_generate_attachment_metadata`), with a recursion guard. * **Asynchronous Bulk Resize**: batch processing via AJAX with a smooth progress bar, percentage, counters, elapsed time and remaining-time estimate. * **Configurable batches** of 1 to 50 images per request, with no limit on the total number of images. * **Timeout protection**: every request works within a dedicated time budget; images not yet processed are deferred to the next request without losses or errors. * **Adaptive throttle**: the pause between batches adapts to the load just processed, so the server is never saturated. * **Mutual-exclusion lock**: only one processing session at a time, even with multiple tabs open. * **Pause**, **Resume** and **Cancel**, with an error log (last 50 entries) and a stored, retrievable session state. * PHP timeout and memory-limit increase applied only to the heavy AJAX requests that need it (queue, batch, restore); light requests and the rest of the site are never affected. * **Optional backup of the original files** with batched restore (up to 25 folders or a time budget per request). #### Security and standards * `current_user_can( 'manage_options' )` checks on every screen and AJAX endpoint. * CSRF protection with a nonce on every request. * Input sanitization and systematic output escaping. * PHP namespace and modular class architecture. * Processing through `wp_get_image_editor()`: uses Imagick when available, with automatic GD fallback. * `uninstall.php` for a clean removal of options, transients and backup folders. #### Requirements and compatibility * WordPress 5.0 or newer (tested up to 7.1). * PHP 7.4 or newer. * Imagick or GD (at least one of them, almost always already present). * No external dependencies or third-party services. ## Screenshots [⌊Settings panel with dimensions, modes and Custom Post Type selection.⌉⌊Settings panel with dimensions, modes and Custom Post Type selection.⌉[ Settings panel with dimensions, modes and Custom Post Type selection.

Upload the `incod-image-dimension-manager` folder to your site’s `/wp-content/plugins/` directory (or install the plugin as a zip). 2. Activate the plugin from the WordPress “Plugins” screen. 3. Go to **Incod Image Dimension Manager Settings** to set the target dimensions, mode and processing scope. 4. Open **Incod Image Dimension Manager Bulk Resize** to process your existing images. ## FAQ ### Are the original images lost? No. If you enable “Keep a backup of the originals”, every file is copied to `wp- content/uploads/idim-backups/` before being overwritten and can be restored from the Bulk Resize screen. ### What happens if the server does not have Imagick? The plugin uses GD automatically. The engine is chosen through the native `wp_get_image_editor()` function. ### Is there a limit to the number of images? No. The bulk process works in configurable batches (1-50 images per request) and has no quantitative limit. Every request has a dedicated time budget: images not yet processed are simply deferred to the next request. ### Can the bulk process get stuck or saturate the server? No. Every batch is stopped when the time budget is reached, the pause between batches adapts to the processed load (adaptive throttle) and a mutual-exclusion lock guarantees that only one session works at a time. If a request times out, the plugin retries it automatically. ### Can I close the page during the bulk process? You can, but it is better to keep it open: the processing loop lives in the browser. The session state is stored on the server anyway and is shown the next time you open the Bulk Resize screen. ### Does it support WooCommerce? Yes. The WooCommerce product is detected automatically among the Custom Post Types, and both the featured image and the product gallery are processed. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Incod Image Dimension Manager” is open source software.
