Protecting your image copyright

Found an interesting resource for photographers today where you can see where your photos show up on the web. Its called tineye. You can upload a file or a url pointing to your image where your hosting it and tineye will search billions of sites to see if it can find your photo existing elsewhere. I found one of my photos stolen through google images. I entered that sites url and came up with yet another site that stole it. If you have any images you’ve been worried about being stolen check out TinEye.com
