This is a great idea, but...<p>One of the big problem with many of the eBay auctions is that they don't use original material - for example, if you're selling a copy of a game or movie, often you won't bother to take a picture of your copy - you'll search online and find the best one you can, slap it in the auction and call it a day.<p>This happens all the time, and as auctions are very time limited, it often doesn't raise the ire of the original source of the media.<p>If they had some sort of dedupe/anti-"stock photo"/anti-"professional product shot" thing in there, this could probably work.
