WordPress utility for cleaning up generated image variations (thumbnails) in bulk, in a wp-content/uploads/{year} directory (all months), and for regenerating thumbnails for specific images.
With every deletion or regeneration, it also updates the attachment metadata in the database to remove references to deleted variations.
Drop the file in the ROOT of your website (not in plugins) and access it via browser directly after you have logged into your WordPress dashboard first. It only works for administrator users.
ALWAYS backup your database AND files before using it. Delete the file after use.
Made to work on WP Engine, but should work on any host.
