I'm no expert on copyrights, but I would think that the pic with his name/copyright on the website would be pretty good proof that it is his intelectual property. He can show that it is the same pic with that info cropped off and ask why it would be cropped if not to remove his name/copyright.

Now, he may not be able to prove this to ebay in 6 hours, or eBay may not want to intervene, but outside of the eBay system, Al has a case to make and if he wants to protect his copyright rights, he should persue.
