The technology has been around for a bit now but before it was a pay feature. Google of course has changed that by acquiring the image recognition software to match your image to what Google finds on it’s search engines. Also, it’s really simple and easy. I’m sure it has a lot of bugs to still work out but I put in a photo that I know has been around a bit that I shot at the 2011 Red Bull Cold Rush this year and the results came up pretty easily.
It’s quite simple.
Go to: http://images.google.com
Click on the camera icon on the right side of the box you type in to search.
Either enter the url of the photo you want to track, or upload that photo and click on search images.
Viola! There are your results, and that’s where people have been putting your stolen photos!
