A lot of TGPs won't list sponsor content galleries - especially if they are pushing the same sponsor.
Nasty Dollars has a fuckload of hosted galleries for their sites. It can now be difficult for a gallery submitter to get posted using their provided content - just because you are now competing with the TGP site.
Nice looking gallery, though. If you are going to keep making nice pages like this (series), feel free to get a partner account on one of my sites:
