How can i use HTML code to make my site background change with each load?

if you go to www.mtv.com, and refresh a few times, you will notice that they have several different backgrounds that change each time you load the page. does anyone know coding i can use to do this too? not changing ever few seconds or at a set time interval, i know how to do that with GIF images. but with each load, theres a different background image.

anyone? anyone?

if anyone can help me out here, it would be greatly appreciated!

thanks!

How can i use HTML code to make my site background change with each load?unblock myspace

%26lt;body onload="backImage()"%26gt;

%26lt;/body%26gt;

%26lt;script language=Javascript%26gt;

var images = new Array("image1.jpg" , "image2.jpg" , "image3.jpg" , "image4.jpg");

function backImage() {

document.body.background =

images[Math.floor( Math.random() * images.length)];

}

%26lt;/script%26gt;

Pretty simple - when the page loads it sets the background image to a random selection from the array images.

Set those images to your picture URLs to see.
