Detect and remove duplicate images on your hard drive
dupeGuru Picture Edition (PE for short) can help automatically find duplicate pictures on your computer and save both headaches and valuable hard drive space.
dupeGuru Picture Edition is actually a spin-off from the excellent dupeGuru, a program designed for doing the same thing for music files so from the start, you know you're in fairly good hands when it comes to duplication apps. The other good thing is, it's also open source too so those with programming knowledge can modify it to their needs.
dupeGuru Picture Edition can detect image duplicates in most of the major formats, including PNG, JPG and GIF. It integrates with iPhoto so you don't need to go browsing around for images to scan. In fact, it can automatically scan your entire iPhoto library. Of course, you may not wish dupeGuru Picture Edition to detect certain images or file types and the preferences give you the chance to tweak it to your liking via the scanning engine settings. dupeGuru Picture Edition also supports PSD and RAW (CR2 and NEF) formats especially for the needs of Mac users.
As regards what to do with your duplicates, dupeGuru Picture Edition can either delete images instantly or move them to another folder. The program features a 'Power Marker' for adding extra annotations to duplicate files. dupeGuru PE isn't perfect, however. One of the problems is that it doesn't always detect duplicates, especially those that are not in any of the major formats. In addition, scanning still takes a long time especially if you've got a big library of pictures.
Most recently, dupeGuru Picture edition has gone through a major revamp of the interface making it much slicker. However, the developer should have concentrated on improving the speed of scanning as many users will find it annoyingly slow.
Overall however, dupeGuru PE is an easy to use and highly customizable tool that will eventually help clear your hard drive of unwanted duplicate images.
