You should take care of the size of your big pictures, the one I just clicked had a filesize of 600kB+, try to make them not bigger than ~100kB. Otherwise some scripts/reviewers will decline your gallery right away, and your bandwidth bill will also become less funny
And try to use less outgoing links to your sponsors, with your 4 actual links, +3 from recips it might happen that some scripts don't let your gallery pass through, as many have a default maximum of 5 outgoing links. So something like 2 links to your sponsor would be ok.
