One thing to keep in mind: the guy in the photo might not be a thief. He might be some random guy the thief/'finder' showed the ipad to, or a guy who works at a pawn shop. He's most definitely somebody who needs finding though if you want that ipad back.
If you're going public with this, there's a bit more to the story that will appeal to the news people. You're in the US somewhere I suspect ('walmart' is called 'asda' here..) and I'm half-way round the world in England. This is a classic 'the power of the internet' story:
- You lost your ipad, but got this one barely-recognisable thermal photo of somebody who's got it, and posted it up on an internet forum.
- An iPad developer in England happened to see it and wanted to do something to help. He recently wrote an iPad2 app called Camera Boost that includes a similar thermal effect, so he knows exactly how to quickly remove it.
- Within 20 minutes of posting the image, you have a clear photo of the guy. Now you just need some help to find the guy and track down your missing iPad!
Guy wants you to promote his app lol.
