About this plugin
Need to know which posts, builders, or meta fields still reference an image—or which uploads are safe to remove?
ProgMaze Media Scanner runs a deep scan of your site: it walks public post types (including templates), reads post_content and post_meta, parses Gutenberg-style block data, URLs, featured images, and nested serialized or JSON values so you get a clear picture of where each file is used and what is unused.
Key Features
- Full site scan — Scans all post types, pages, custom post types, templates, and reusable blocks.
- Gutenberg aware — Parses block JSON attributes (core/image, core/gallery, core/cover, core/video, core/file, core/media-text, and more) to find media IDs.
- Page builder support — Scans media used in Gutenberg, Avada, Elementor, and similar setups that store IDs or URLs in content or meta.
- Featured image tracking — Detects when a media item is used as a featured image on any post or custom post type.
- Post meta scanning — Finds media in ACF fields, WooCommerce product galleries, and other plugins that store attachment IDs or URLs in meta.
- Usage detail view — Open any item to see every post that uses it, with Edit and View links and usage type (content, featured image, meta, gallery, setting).
- Safe deletion — Only unused media can be deleted directly; used items can be detached first or removed with Detach & Delete.
- Bulk delete — Remove multiple unused items in one action.
- Incremental updates — Saving a post re-scans that post only, keeping the cache fresh without a full rescan.
- Filters — All / Used / Unused, mime type filters, and search by filename.
- Library overview — On the main screen: total storage, image vs non-image space, space by file type (bars), largest uploads, and most-referenced media (cached for performance).
Supported for
- WordPress Gutenberg (core blocks)
- Elementor
- Avada
- ACF (Advanced Custom Fields)
- WooCommerce (featured image + gallery)
- Builders that store media URLs or IDs in post_content or post_meta
How it works
When you run Scan All Media, the plugin rebuilds its usage cache: it inspects content and meta for attachment IDs, upload URLs, _thumbnail_id, WooCommerce galleries, and nested structures. Each link is stored with a usage type. Saving a post triggers a targeted re-scan for that post only.
On Media → ProgMaze Media Scanner, filter by used or unused, narrow by type, search by filename, use View Usage for details, and delete or Detach & Delete as needed. Deletions are permanent—back up first.
