Try putting the background configuration in the css rather than in the "header.tpl"...one less thing to have to monkey with when a new update comes out.

templates>css>style.css

It's the first order of things and should look like this:

Code:
body {
font-family: Arial, Helvetica, sans-serif;
font-size: 12px;
background-color: #CCCCCC;
color: #222222;
margin: 0px;
padding: 0px;
background-image:url(http://sca-video.com/templates/images/bak.jpg);
}
This is exactely why I wish the colors and stuff for the templates was all in the CSS. Would make modifying it so much easier and save a big headache with each update for those of us who have made changes to the templates.
