Ok here's what I've learned as a complete veteran noob to galleries so far.
You can use chameleon to pretty much do everything but design your gallery template. We made a custom system that we just upload a zip of 20 or so images to our server, and then it automatically unzips, renames, copies, creates various thumb sizes, and puts them in a standard template with the proper site calls from our DB.
The result is like this:
http://www.pornsumer.com/galleries/big-naturals/1/
So what I wanted to do was just have Chameleon take this page, inject the recips, re-write me some HTML files and then submit them.
Unfortunately these galleries above don't really have an .html file I can download, they're all created on the fly, so we have to write something that will generate an index.html for each gallery, for Chameleon to work with.
As for thumbnails, the thumbs I already have created are fine using our system, so apparently we just use Chameleon to create 2 "thumbnail preview" images for TGP's to use on their front page, to link the galleries with.
So I'm almost there, but need physical .html files atm. Thanks for everyone's help.
