[Plugin: NextGEN Gallery] Newbie needs to understand setup

I’m new at WP and at NextGEN. I’m coming from using Menalto’s Gallery (not in WP). I’m used to the top level being the Gallery and then having nested albums within. It sounds like NextGEN has flipped the language so the main installation is an ALBUM and then it has Galleries in it?

I’ve successfully made a couple of Galleries. What I’m not getting is how do I make a page with thumbnails that then link to these Galleries. Ideally I’d have a page in my navigation called Gallery and on it would be 9 thumbnails, each linked to another page that each have 9 more thumbnails. Each of those would open a slide show. Clear? POSSIBLE? HOW?

If this is beyond the scope of forum help maybe you could point me in the right direction. I’m not a programmer and am struggling with this.

Thanks!
Sheila
