LMAO @ Steve. Great tips for building a high traffic site
If you're using sponsor content on the gallery then you need to leave it as is, copyright violations and all that.
If its your own content and the sponsor isn't converting, just run a search and replace proggie and change the links to another paysite in the same niche. The gallery will look the same to the surfer and the TGP owner, but when they click they'll go to a different paysite.
On another note, if TGP archive and SE traffic is burning up more bandwidth than you can afford, you really ought to consider a new line of work.
