Picture behind blog & module area but not as background/wallpaper? Options

[PuppyLove72]

Alright, I've noticed that on some layouts they have a photo or pattern (usually a pattern) behind their left/right side modules (if they have them), and the blog area and anything that's not the background (except the ad). I was wondering how that's done. I assume it's a code, but I can never find it. So far, I've only figured out how to put a color behind the area (like in my audrey hepburn layout here).

Help, please?

ohhhh, i see what you're talking about now. i was confused at first.

add this part to your code somewhere.

CODE

table.navigation, table.main, table.footer {
/* the width of your blog with modules */
  width: 350px;
  background-color: #000000;
  background-image:url();
  background-position:center;
  border: 1px solid #FFFFFF;
}
