Step One:
---------
Make a background image and add it to your page
as you normally would, like this:
Code
<body background="someImage.jpg">
Step Two:
---------
Insert the following script immediately *after* the
tag:
Code
<script>
<!-- // Source: CodeFoot.com
// set the speed
// larger numbers = slower scroll
var howQuick = 10;
// do not edit below
// -----------------
var beIE = document.all?true:false;
var iWhere = 0;
function scrollBackGround(){
if (beIE){
iWhere = iWhere + 1;
if (iWhere > 1000000) iWhere = 1;
document.body.style.backgroundPosition = "0 " + iWhere;
window.setTimeout("scrollBackGround()",howQuick);
}
}
scrollBackGround();
//-->
</script>
