Ok i've worked out that this code will put a gap above my myspace nav bar
<style>div.topbanner {
top: 0;
left: 49%;
margin-left: -387px;
width: 100%;
height: 636px;
position: absolute;
}
body{
background-position:top center;margin-top: 660;}
</style>
Now how do I fill this gap with a picture????
Cheers
