Install
This is the repository archive. It installs, but the folder name will carry the branch suffix and updates will not flow.
Install straight from GitHub with WP-CLI:
wp plugin install https://github.com/wpranger/wpr-rebuild-meta-data/archive/refs/heads/master.zipNo built-in updater. New versions won't appear under Dashboard → Updates. Install new releases yourself, or let Git Updater track the repository.
Simple plugin to rebuild corrupted WordPress image meta-data.
Installation
Upload to wp-content/plugins and activate.
How does it work?
Visit the WordPress Dashboard Tools Menu:
Click on Rebuild Meta
The plugin runs. You must then rebuild your thumbnails with a suitable tool.
I like Force Regenerate Thumbnails:
