MRN Media Tools

Extensible WordPress Media Library utilities. The canonical source lives in the independent mrnwebdesigns/mrn-media-bulk-tools repository; MRN uses a local checkout symlink for stack integration. The first module adds bulk metadata updates to the Media Library list view.

Current Modules

• Attachment actions: Hide WordPress's attachment-page View action and group all Media Library row actions in one keyboard-friendly menu. Destructive actions are kept at the bottom and styled separately.
• Bulk metadata tools: Update attachment titles, image alt text, captions, or all three for selected Media Library items.
• Inline metadata editor: Review paginated attachments in a dedicated workspace; filter by media type or missing fields; and edit title, image alt text, caption, and description per row. Changed rows are selected automatically and can be saved together or one at a time.
• Dimensions column: Show image width and height in the Media Library list view from core metadata, with a bounded SVG-header fallback.
• HappyFiles folders column: Show every folder assigned to an attachment, including clickable parent paths for nested folders and an Uncategorized state.
• File size column: Show a human-readable attachment size from WordPress metadata, with a safe fallback to files stored inside the uploads directory.
• List filters: Narrow media by exact MIME/file type, minimum file size, and detected usage count using the file-size and usage indexes.
• Generated image sizes: Inspect the derivatives WordPress actually created, including size name, dimensions, file size, and a direct view link.
• Column controls: Resize shared boundaries by pointer or keyboard so the adjacent column compensates and the table width remains stable. Boundary handles sit on the left edge of the following column so they remain usable while horizontally scrolled. The last column has its own table-edge handle, and a synchronized scrollbar above the table keeps horizontal navigation available. Auto-fit a column to its largest item, save widths per WordPress user, and open native column visibility controls from a convenient Columns button.
• Usage index: Scan detected references in editable content, featured images, and media-like custom fields; refresh the index daily with WP-Cron; and inspect matching content in an accessible modal from the Used In column.
• Filename tokens: Build values from {file_name}, {file_title}, {file_basename}, {file_extension}, {mime_type}, and {mime_subtype}.

Compatibility

The release unit intentionally retains the mrn-media-bulk-tools folder, text domain, action identifiers, class name, and transient prefix. Existing installations therefore continue to update in place while the displayed product name and internal bootstrap support a broader media-tool scope.

Usage results are intentionally described as detected references. Media added dynamically by theme/plugin code or stored in an unknown external format may not be discoverable through a WordPress database scan.

Runtime browser, accessibility, API, and performance checks should be run separately against an explicit target site when this plugin change affects rendered output or live WordPress behavior.
