Image Comparing Software

Before I reinstalled Windows I used a program called Image Comparer to find duplicate images. It was a pretty awesome program.
Anyways, I installed 2.3 and I can't find a working patch/crack/serial for it (surprisingly the one from SnD didn't work)
Anyways, I'm looking for a program very similar to Image Comparer, as in, the methods it compares images and the UI.
Or a working crack for IC.

In before b& etc.

Thanks for the info kind sir, so does GQview look for possibly duplicate images / same H pic with fuzzy comparison? It's trivial to detect exact identical files; I need something like DupDetector that will let you know of images that look similar even if the files are different (even across different file formats) for Linucks.
