Delete duplicates upon detection or mark them with a keyword to make them easily found using iPhoto features like search or smart folders.

Detect duplicates by using file specific data like filename, dimensions, file size, Exif creation date or date of creation.

Detect duplicates using effective algorithms using electronic checksums like MD5 and CRC32.

Compare images using different algorithms to detect och understand differences.

When found the duplicate will either be marked with a description of your choice to make it searchable or simply moved to iPhotos trash-can. While I hated to pay 7.95 for a program that hopefully Ill only need to use once (although I may need to do so again somehow I managed to bypass iPhotos duplicate protection and end up with duplicates even on photos taken after I started using iPhoto), I bit the bullet.

Easily find and annihilate duplicates created internally by iPhoto or during import. Duplicate Annihilator takes on the time consuming task comparing the images in your iPhoto library using effective algorithms to make sure that no duplicates escapes.

Yes nowadays iPhoto protects you from importing duplicates but if you are like me you have managed to do so anyway.Дuplicate Annihilator takes on the time consuming task comparing the images in your iPhoto library using effective algorithms to make sure that no duplicates escapes.
