   List of all resized images in uploads directory with options to select and delete

Installation Instructions

What parameters are used to determine if a image is resized?

After looking at all files in the WordPress uploads directory, a file is determined as resized when three criteria are meet:

1. It’s an image
2. The file URL is not a main WordPress Media Library file
3. The filename ends with -###-###.

What is this warning about `chmod` about?

The method of deletion only works when the server allows PHP to edit the folders contents. CHMOD is the permission settings for files and folders. If you’ve received a warning of this, the CHMOD on the upload directory is too low.

It says I have no resized images, but I do

Please note this is a new plugin (rewritten summer 2017), this plugin was developed and tested in only two server environments – variables on your setup may of not been considered while developing. Please open a request in the Support tab and provide as much info as you’re willing to give to help resolve this issue and ensure this plugin works on all setups:

• WordPress & PHP version
• Location of directory
• Wether or not files are stored in year/month sub folders
• ect.

How do I backup my files?

The plugin insists on backups as it removes files permanently, you can ignore and bypass, however you should always backup your WordPress installation
