This is a small Windows program written in Lazarus and Freepascal that uses the DHash image hashing algorithm to search folders and subfolders for identical, near-idential or similar images, including cropped versions or those with different resolutions.
This program does not require installation (just extract to any directory).
The image hashing algorithm (DHash) is by Dr. Neal Krawetz, who writes at Hacker Factor.
