n00b needs help on background image

[TwinsForMe]

I'm running 3.0.7.

I'm in the Style Manager --> Main CSS --> ?

? where/how to put code:

background-image: url("image_pb/misc/Twing.jpg");

I would like to have a background image appear like the background image at this site.

Place the code in the Body panel. Where it says standard CSS Attributes, place it into the Background box so it looks like so:

url(images/pgn/misc/bg.gif)

Hope that helps :)

That didn't work. Here is a screenshot of the CP:

I figured it out. Thanks. :)

Would you mind explaining how you did it? I'm totally new at this and I'm having trouble with the background. I've put in the code and it doesn't show up in my testforum.
