Duplicate Image Detector enables you to find duplciates in your image collection. Image comparison is done at the pixel level, so changing image formats will not stop duplicate images being detected. Directory comparisons can be run so you don't end up importing duplicate images into your collection.

Limitations: Duplicate Image Detector will run in free mode for an unlimited time. Duplicates and comparisons can be run without any limitations. When runing in demo mode the only limitations is you cannot perform any actions on duplicates that have been found.

Requirements:
OS X 10.4-10.6
Universal Binary
