I don't like blind links too, but do you have actually the right to img src another site? Thats even more primitive than blind links. Just tell the guy, you don't like his site and/or galleries and that's it.
Anyway, you can always block any domain by .htaccess and tell about multiple request to your host, so he can block all that shit from a system level. Also, requests like that are similar to DoS attack if they come from a site with a lots of traffic like 'thehun.net'. This is illegal and blind links are, erm, just annoying. So you are with IMG CRC/IFRAME risking a legal case for some stupid fuck who likes to blind link.
