dupeGuru Picture Edition 2.4

dupeGuru Picture Edition (PE for short) is a tool to find duplicate pictures on your computer.
It works like dupeGuru, but is specialized for duplicate pictures matching. dupeGuru PE runs on Windows, Mac OS X and Linux.Not only can dupeGuru PE find exact matches, but it can also find duplicates among pictures of different kind (PNG, JPG, GIF etc..) and quality. On Mac OS X, dupeGuru PE can scan your iPhoto library. You can tweak its matching engine to find exactly the kind of duplicates you want to find.
Its engine has been especially designed with safety in mind. Its reference directory system as well as its grouping system prevent you from deleting pictures you didn't mean to delete.
dupeGuru PE supports JPG, PNG, TIFF, GIF and BMP formats. All these formats can be compared together. The Mac OS X version of dupeGuru PE also supports PSD and RAW (CR2 and NEF) formats.
