You do it in the stylesheet. This is a snippet of the stylesheet in use on the Fan Odyssey site in my sig.
Code:/*wrappers - page or section containers*/ #mainWrapper { background-color: #000000; background-image: url('../images/space011.jpg'); text-align: left; width: 100%; vertical-align: top; } #logoWrapper{ background-image: url('../images/space011.jpg'); background-repeat: repeat-x; background-color: #000000; height:110px; width: 100%; }
