You make a gallery with you gallery maker, then duplicate it with Chameleon. Reason being is that most TGPs require a reciprocial link or banner. Instead of creating 300 html files in your gallery maker by hand, the Submitter now does the job for you, by automatically creating a html file with a recip link already in it. Lets say you make a gallery "index.html"
The big asses TGP wants a reciprocal link. Chameleon dulicates you index.html and calls it bigasses.html and inserts a banner bigasses.jpg on top.
This gallery now gets uploaded to your server, after, the submitter submits
http://....bigasses.html to Bigasses TGP. Their script checks the gallery and finds the recip link.
