I just want to throw in a few ideas.
I'm thinking TGP2 will need something different and something that will make surfers want to come back and check out the galleries.
1. Come up with a creative name for the type of post it will be. This is a big one, the name should be something that makes them want to check out these new type of TGPs.
2. The galleries need to have something more desirable to them to want to keep viewing them. Not so much that they don't go to a sponsor.
I'm pretty new to all of this but I would like to suggest something, why not add a few words under the linked pics, the others just say sample, and let them know if they want the rest of the story so to speak to check out the sponsor.
Here are 2 examples of this type of gallery.

This might take a little creativity, but look how creative everyone is with different ways to send traffic.
From the little experience I have, those galleries there get 20 times more click thrus to the sponsor then with out a few words or sorta story.
Just a few ideas
