One thing that might bear mentioning here...
When Ramster says he easily made a profit, readers should take into account that this may be either based on a pre-tested gallery or at least on a gallery built by an experienced builder/submitter.
My point is that your results may vary dramatically from this if you build your very first gallery, pay for a gallery spot and wait for the signups to roll in.
If you're just starting out, and don't have a big budget for paid gallery spots, it might be best to use free submissions until you figure out how to make tgp galleries convert for you.
Now, Ramster may come back and tell you he did that with the very first gallery he ever built and blow my advice out of the water. But I'd wager the other way.
