Hi Anny and welcome to the Board.
If you're looking for places to submit your tgp's too, try this page for some fast links:
As you read their webmaster pages you'll find sites that offer partnerships, and usually they have a form or an email address where you can directly ask for one. One thing though that will help you get those precious partnership accounts is to have some galleries that aren't made from sponsor provided images. Most have been submitted by thousands of others out there, and the tgp owners quickly get sick of seeing the same pics over and over. We've had a much better success rate of getting a partner account when we can show some purchased content galleries to push our sponsors.
Overall, I thought your galleries looked good, so it looks like you've got a handle on how to set them up!
