Try like this..

XML

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <script src="jquery-1.10.2.js" type="text/javascript"></script>
    <script type="text/javascript">
       var loading = function () {
            var totalCount = 6;
            var num = Math.floor(Math.random() * totalCount) + 1
            document.body.background = 'images/' + num + '.jpg'

        }
    </script>
</head>
<body onload=loading();>
    <form id="form1" runat="server">

This is a nice approach, ASP.NET also provides a control to achieve this.
You can use ADRotator control for doing this.
