As you can see, there are many parameters that can be set, but the GUI does not try to impress you.

As it name indicates, this small utility is aimed at finding duplicate images. It basically scans set of pictures (or whole library) and finds duplicities or very near exact copies of images. In case of near exact match, it will show you previews of both and option to pick which one shall be removed. Image Deduplicator can also match same pictures that are in different resolutions or image formats. It's a freeware.
