From the developer:
Easily find and delete duplicate images on iPhoto '09 (version 8.x) or later. You can customize the search criteria. After search, you can use auto-marking to automatically mark duplicate photos for deletion to iPhoto's trash. Currently it has auto mark by date, title length, file size, image size, has RAW and rating.
PhotoDedupo can find both exact duplicates and similar(slightly modified) duplicates on iPhoto.
You may want to check out more Mac applications, such as Dock Changer, PDFGarden or AppMenuBoy, which might be similar to PhotoDedupo.
