Duplicate Annihilator

Yes, nowdays iPhoto protects you from importing duplicates, but if you are like many people, you have managed to do so anyway.

Duplicate Annihilator takes on what otherwise would be a time consuming task of comparing the images in your iPhoto library. By using advanced algorithms to make sure that no duplicates escape, Duplicate Annihilator is both fast and efficient. When a duplicate is found, it will either be marked with a description of your choice to make it searchable or it will be moved to iPhoto's trashcan.
