Image files use up a lot of hard-drive space, and searching for multiple copies of photos can be time consuming. Duplicate Annihilator for Mac helps identify extra copies of the same photo in iPhoto and allows the user to tag the duplicates.
Duplicate Annihilator for Mac searches for duplicate photos in iPhoto. The program is able to remove or tag photo duplicates. When copies of the same photo are found, the program tags one as the original and the rest of the copies as duplicates. This program includes many modifiable elements for searching and tagging of duplicates. This free version allows you to compare up to 20 selected photos at a time or 500 random photos. The limitations on this version prevent you from seeing how long a scan of more than 500 photos would take. This program is definitely made to help organize huge photo backlogs, but unfortunately the free version is restrictive. The full version costs $7.95.
Duplicate Annihilator for Mac seems to be a useful program, but the free trial restricts an accurate assessment. This version would be suitable for personal use as long as you have a limited number of photos in iPhoto. Without the trial restrictions, the full version may be suitable for regular use by amateur photographers.
Editors' note: This is a review of the trial version of Duplicate Annihilator for Mac 4.4.1.
