Scan and delete unwanted auto-generated WordPress images and save huge diskspace. Delete thumbnail sizes (started or ended with 150px, 280px 300px or 1024px) and move them to a trash folder inside your uploads directory. Preview and restore images from the trash.
Whenever you upload an image, WordPress creates three additional resized versions of that image. This increases your hosting inodes and unnecessarily occupies disk space.
