First of all, you never freak out when your trying to get something you want instead of need
And wait a little before PM'ing people over something this simple lol....
AdminCP --> Styles & Templates --> Style Manager --> Select the style, use the drop down box to select main CSS, then look at the top of each until you find --> Page Background (Customized in this Style)
Then it says background... use html colors to achieve this, simply google html colors, click images and find a chart!
#000000
#ffffff
etc
etc
Also, like I said above, be a little more patient and read my sig

Edit: NM about the simple comment, about 6 months ago I had no clue where most of this stuff is! I just learn fast is all

Ohh yeah... forgot to add this!
Let's say you choose the one that says --> Body (Customized in this Style)
In that same field you can do the #000000 etc but like this:
Code:
#F0F1F3 url(yourfoldername/yourimagename.gif) repeat-x top left
So basically it will pull an image to use
see the name yourfoldername, it's an actual folder in my forums root (not name that though lol but as an example), so simply create a folder and place the image you wish to use in there
Tinker w/ that! also look up CSS and then scroll all the way to the bottom, now add in your own additional tweaks
