[Plugin: NextGEN Gallery] Help With Album Layout

Hello there,
I’m afraid I’m a bit of a newbie when it comes to CSS.

I’m having a few issues trying to change the album layout.

Here’s what I’d like: Three column gallery thumbnails displayed per album (Three gallery thumbnails per row), description centered under each.

I’ve searched and searched and can’t seem to find the answer. Any help would be wonderful.
