I have talked to many webmasters about tgp's. Most of which prefer using thumbs (88x88 or large) as their gallery links, but when trading with other tgps that only use text the prod is different. So they trade with other sites like they have.
So, I was thinking, what about a tgp that has both. Let the surfer decide which one he/she wants. By default the tgp loads with text links, but they can turn thumbnails on if they wish.
