About this tool.
Image Alt Sync scans selected posts and updates any <img> tags found in the post content that reference media items (class wp-image-### ), and replaces their alt attributes with the attachment’s _wp_attachment_image_alt value: – If the image is in the Media Library, it prefers the attachment’s Alt Text. – If no attachment alt is set, it falls back to the image filename (without extension) or the post title (configurable in the UI). – Optionally skip images that aren’t found in the Media Library. – Optionally restrict by image file extensions (e.g. jpg,webp ).
Run in dry run first to see exactly what would change. The log shows each post processed and any per-image alt changes.
Highlights – Processes per post in batches with a customizable delay (default 100 posts, 1s). – Filter by post status and date range (quick buttons: Today, Yesterday, Last week, Last month, YTD, All). – Validate that “Date after” ≤ “Date before”. – Limit by Post ID range with buttons to auto-fill lowest and highest post IDs. – Skip posts without <img> (optional). – Exclude image extensions (comma-separated, e.g. .svg,.gif ). – Dry run (browser & WP-CLI) shows clickable post IDs, post titles, filenames , and detailed old → new alt replacements. – Only processes posts that have at least one image attachment .
