Many surfers are use to click a gallery link, check out the gallery and click back and check out the next gallery. So you can get more than 1 click and therefor more than 1 credit from one surfer. If you include skim then the same thing there, the surfer might click back after seeing the other tgp.
Hopefully, you'll get some signups from your tgp, and if so, use some of that to invest back into your tgp by buying traffic to keep the ball rolling.
