it didnt work??
this is what I changed it too based on a few examples I found... body> wasnt used in the ones I saw....
Code:
div a
{
position: absolute;
top: 0;
left: 0;
width: 100%;
height:  100%;
background-image: url('bg_main.jpg');
background-repeat: no-repeat;
background-position: center;
background-color: black;
}
