Help with forum background image

[S S0DEN]

I need some help coding my forum background to match my main page. Currently, my background is a solid dark grey http://sodenbowl.com/forums

I would like it to match my new homepage once I get the home page like: http://sodenbowl.com/madden

The stadium on both sides that is taken from one large .PNG then i believe the repeat is the grey just below that the stadium fades into.

Thanks in advance guys,gals.

Did you try going to the Style Vars>Common>body_background then in the box below where you choose the color put in the url to the image you want to use:
i.e. url(images/name-of-image.png) - or jpg or gif or whatever type image it is.
