Lee is right. This is a business and an investment. Nothing happens quickly unless your doing something different and amazing.

Theres debate about this, but in my experience the money from running a tgp comes from people who return to your site over and over, and learn to trust you.

And what is "many visitors"? a few hundred a day? 10k a day?

If your new site has "Many visitors a day" this early in its life then its probably poor quality recycled traffic you bought or traded, and poor quality traffic rarely buys. Theyre just clicking clicking clicking until they find that 1 guy they like who they can jerk off to.

As for your bandwith, your pics are 160x120 and wayyy too big and people on slower connections will leave your site after a few seconds.
most successful mgps do 88x88 or 120 x 90.
