Image tracking by unique id

Interesting article here http://boingboing.net/2011/08/24/photographer-gets-9k-worth-of-stolen-camera-gear-back-with-gadgettrak.html.

Interesting in that every picture you upload to flickr is tracked regardless of the login you use ...

Nice to know that stolen cameras can be found so easily

It works provided you don't erase the Exif first I would have thought.

Brilliant, but as someone hinted on that thread, how many police forces would bother to follow up on it with the limited manpower at their disposal
