Worked great, found over 3,300 duplicates

After a crashed harddrive a few years ago, I ended up with many duplicate photos in iPhoto (I restored photos from multiple places - and then restored my whole backup, hence all of the duplicates). This program worked like a charm. It took about an hour to scan the 20,000 photos in my iPhoto library and then another 15-20 to move the dups to trash. In all, this saved me hours upon hours of sorting through photos. Very satisfied.
