If you have been a victim of a lost or stolen camera, GadgetTrak might be able to help you locate it. You simply type in your serial number into the search bar and it tracks to see if someone else has posted images from your camera on photo hosting sites. It works because the information kept on every photo taken by any individual camera has information. Some of that information is the serial number of the camera, embedded within the file. Once you type in your serial number, the search engine looks for photos containing that embedded serial number. If you lost a camera, give it a try and see.
