Hello!

I m creating an application and in that i m having the login form which is being given an background image(.jpg). Now what i want is i m having a set of six different .jpg images and i want that everytime the user comes on the login page the background image should be changed or it should even be changed if the page is being refreshed. Help me out ...

Thanx in advance,
bhavin...

<script language="javascript">
var bg = new Array("bg1.jpg","bg2.jpg","bg3.jpg","bg4.jpg","bg5.jpg","bg6.jpg,");
function putBg(obj){
index = Math.floor(Math.random()*(bg.length-1));
this.background = bg[index];
}
</script>
</head>
<body onload="putBg(this)">

try this:

<script language="javascript">
var bg = new Array("bg1.jpg","bg2.jpg","bg3.jpg","bg4.jpg","bg5.jpg","bg6.jpg,");
function putBg(obj){
index = Math.floor(Math.random()*(bg.length-1));
obj.style.backgroundImage = bg[index];
}
</script>
</head>
<body onload="putBg(document.body)">

if that doesn't work, then you may have to change the line in bold, so that it looks like this:

obj.style.backgroundImage = "url(\"" + bg[index] + "\")";

hope that helps
