Duplifinder finds the duplicate photos and videos in your iPhoto Library.
It shows you each original with its duplicate(s):
Please Note: Duplifinder only finds exact duplicates, much like iPhoto does when you try to import duplicates. It will not match photos that are different size, cropped versions of other photos, "enhanced" or modified photos, etc.
