How does that work? I don't see any imbeded URLs in the image.

Image poker chips contain embedded URLS :

Or was the auction somehow different than the image you put up here. For instance, including, poker chip images that contained embedded URLS?

Seems like they would have to end half the auctions on eBay if it was just for having a website listed on the image. People use their website name to protect images, all the time.
