Description
Radermacher AI Media Marker does one thing at production quality: it labels
AI-generated images in your media library and renders a clear, accessible
badge on the frontend — injected server-side into the HTML, so it works
with every page cache and never flickers.
What it does
- Mark images as AI-generated in the media library (single, bulk, or WP-CLI)
- Automatic detection from IPTC/XMP metadata (
DigitalSourceType) and C2PA
manifests on upload — deterministic signals only, no guessing - Filename-based suggestions (Midjourney, DALL·E, …) that you confirm —
the plugin never auto-marks from heuristics - Server-side badge injection for core blocks: Image, Cover (including
background variant), Media & Text, Post Featured Image (including Query
Loop), Site Logo — plus theme template images and Classic Editor content - Localized, accessible badge: real text, screen-reader label, no
JavaScript, cache-proof by design - Machine-readable marking: write IPTC/XMP
DigitalSourceTypeinto all
image sizes — pure PHP, lossless (files are never re-encoded), works on
every host, with a verify/repair command against optimizer stripping - WP-CLI for agency workflows:
wp aiim scan,mark,list --format=csv
(audit export),write-meta,verify-meta
What it deliberately does not do
This is not a compliance suite. No readiness scores, no chatbot notices,
no assessment wizards. Depth over breadth.

FAQ
Is the plugin really free — also for commercial use?
Yes. The plugin is free software under the GPL, for every kind of site, with no feature restrictions. If it serves your business, you can back its development with a voluntary supporter license (a small subscription with a certificate naming your domains) — entirely optional, the plugin works identically without it.
Does the badge work with caching plugins?
Yes, by design. The badge is part of the server-rendered HTML, so it is inside whatever your page cache stores. There is no frontend JavaScript.
Does this plugin guarantee EU AI Act compliance?
No. It is a technical tool that supports the transparency obligations of Article 50. It does not constitute legal advice and does not guarantee compliance.
Does the plugin use the official EU icons?
Yes. The “EU label” and “icon only” badge styles use the European Commission’s official icon for labelling AI-generated content (published 10 June 2026), bundled locally — no CDN. Per the Commission’s own guidance, using the icon does not by itself establish legal compliance.
Can I show only an icon instead of the text badge?
Yes, as an opt-in “icon only” style. The screen-reader text and a tooltip with the full disclosure always remain. Be aware: an icon alone may not satisfy the “clear and distinguishable” requirement of Art. 50(5) EU AI Act. If you use this style, add a clearly visible explanation on the page (for example a footer legend) and review the choice with your legal counsel. This is not legal advice.
HTML badges cannot reach those contexts. The metadata layer (IPTC/XMP DigitalSourceType written into the files) is the answer there.

Changelog
1.0.2
- Renamed to “Radermacher AI Media Marker” (slug
radermacher-ai-media-marker) following wordpress.org review feedback
that the previous name was too generic. Functionality, settings, and
markings are unchanged.
1.0.1
- Renamed to “AI Media Marker” (slug
ai-media-marker) following
wordpress.org review feedback on the previous name. Functionality,
settings, and markings are unchanged. - Admin CSS/JS (media list column, settings page preview and scan) now
delivered via wp_add_inline_style/wp_add_inline_script instead of
printed tags. - Hardening: metadata writing refuses any file path that resolves
outside the uploads directory, even if attachment metadata was
tampered with. - Translations now come from translate.wordpress.org language packs;
the German translation files are no longer bundled.
