Duplicate Image Detector will hunt through your files and directories, detecting images which are identical or very close to identical. No longer will your hard drive be full of the same image copied over and over. Avoid slowing down your website by making users load the same file multiple times.
Duplicate Image Detector will even detect images which are saved in different formats but have the same source. If you have a tiff file which has then been saved using different jpeg compression settings Duplicate Image Detector will find all of those images even images that have been scaled.
Once you have found the duplicate images you can compare the matches and inspect the images.
