Image Alt Sync scans selected posts and updates any <code><img></code> tags found in the post content that reference media items (class <code>wp-image-###</code>), and replaces their <code>alt</code> attributes with the attachment’s <code>_wp_attachment_image_alt</code> 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. <code>jpg,webp</code>).
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 <code><img></code> (optional). 
– Exclude image extensions (comma-separated, e.g. <code>.svg,.gif</code>). 
– 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.

Tips 
– Use the “Lowest ID” and “Highest ID” buttons to auto-fill the ID range. 
– Use the extension filter (e.g. <code>jpg, jpeg, png, webp</code>) to target specific image types. 
– Check “Skip images not in media library” to avoid external or missing files.

This plugin handles a number of things:
<ul>
<li>An extra “create post” option in the row menu for mediaitems in the listview</li>
<li>An new “create post featured image” bulk option</li>
<li>add some code to make sure that when you delete a post, the image is cleared properly (post_parent = 0) so it shows up in the “unattached” filter</li>
<li>add MediaRSS to your feed. </li>
</ul>
By default it create “private” posts as I needed this plugin to deal with older photos. As I use the image postdate as 
default for the postdate, private leaves this date alone which publish and draft->publish by default moves the postdate 
the date of publishing. Private is also easy to find in the “posts” window. 
They also get an “media2post” tag so they are easy to find. 
De owner of the post equals the owner of the image.
Special thanks go to mr. Jeremy Felt who wrote “Automatic Featured Image Posts” and who’s code heavily 
“influenced” this plugin. I learned a lot from his code!
