Can the Pope copyright his image, like other famous people do so that if anyone wants to make merchandise with his likeness on it, they have to pay for a licensing fee or pay royalties or the like?

I’m seeing all the stupid Pope-Merch in the US right now and it is rather sickening. Think he’ll toss some tables in the stores and go all Jesus-at-the-Temple on them? Should he get royalties for the stuff? What should he spend the money on then? Any suggestions for what sort of new products he should come out with? Of course, I’m partial to Pope Soap on a Rope. No surprise there.
