Hashes To Detect Resized Images

So, I have lots of photos, and some are duplicated on several web-sites, with no reference to the original source. I want to detect matches, so I can move them (and their associated meta-data) all to a single yet-to-be-determined destination.

But here’s the snag. Some of the photos have been made into different sizes and qualities for web-viewing. It would save me time if I could automatically detect this. I need an equivalent to SoundEx that works on images, so images have the same hash even if they are resized.
