Hello,
I would like to share this gr8 new service from ImageBunk.com. Yes they allow adult.
They let you add all ads on image pages of your choice. 2 x(300 x 250) & 1 x(160 x 600). So without making sponsors unhappy. You can just start uploading your galleries with your related ads, sponsors whatever & link the images & galleries using the thumbnail html, bbcodes. For more info check:

I believe this is something you will like as a tgp owner & save a lot of bandwidth.
cheers
