I was tipped off to this website last night at the Smug Mug Maui- Photographers group. "Image Rights" is essentially a registry for you to upload your images and they then scan the internet for other websites that have ripped them off. The interesting part about this is once they find an infringing party, they go after them to collect money. The Photographer and Image Rights then split the money. Interesting idea. There is a free account and paid account, the only difference being the amount of the split of money (50/50% vs 65-35%).
