[Plugin: NextGEN Gallery] Different looking galleries

Hello!

What if I wanted two different-looking kind of galleries? I haven’t been able to figure that one out. There are (going to be when I figure this out!) two parts to my site – my regular photography, and my wedding photography. The differences won’t be massive, but they are enough that I can’t figure it out on my own. A little bit of help would be great.

To go into details:
Right now I’m set up with about galleries which are each presented as 2 rows of 12 thumbnails, which upon click open the full size pictures in LightBox. I’ve modified the css and changed the appropriate options to make this work. The new wedding section on my site should have 5 rows of 5 thumbnails… So in “options”, it wouldn’t be “24″ images per page anymore, but “25″, and the CSS would be different on a bunch of things that I don’t always fully comprehend like alignment and floating… etc

Any idea how to make this work? Is it even possible, or do I have to install wordpress in another directory and start over… just for that?

I’d really appreciate any help or feedback. Million thanks!
