What It Does

This plugin behaves similarly to Regenerate Thumbnails except that images are resized automatically on the fly when they are used. Once created, they won't be processed again.

Your thumbnails will now resize when image sizes in Settings > Media is modified or when switching themes and plugins with different thumbnail or featured image sizes.

No settings pages are needed; just install and activate, and things should work right away.

To test it out, create a gallery using the Add Media button while editing a post or page and use thumbnails. After changing the thumbnail size in Settings > Media, refresh your gallery to see the new sizes.

OTF Regenerate Thumbnails fixes the issue of thumbnails not updating to the new sizes automatically.

For developers, ensure your images get resized properly by using WordPress' image functions to display featured images and image attachments.

Features include creating resized thumbnails on the fly, handling image size settings changes, and working automatically without setup.
