Need help integrating gallery2 into website

Right now I am working on a website using dreamweaver and a CSS. The website basically is divided into 4 sections, with a main body. Because of this, the picture section needs to load into the main body and be very simple. This means gallery2 must display downgraded without any of the gallery attributes except for the albums and pictures.

Please look at this website photo section, http://siriux.net/photos/main.php

Apparently this guy is using the siriux theme, but his own photo album is more simplified than the downloadable theme. My question is how can I do this? Maybe there is a theme out there that does this allready or not... I do not know but I spent about 2 hrs looking without success.

Just trying to keep it simple, please help me.
