    Need help with code!

    I need these ads to be random not in order... how do i do this?


    <head>
    <script language="javascript">
    var theImages = new Array() // do not change this

    // To add more image files, continue with the
    // pattern below, adding to the array.
    theImages[0] = '1.jpg'
    theImages[1] = '2.jpg'
    // etc...

    // do not edit anything below this line

    var j = 0
    var p = theImages.length;
    var preBuffer = new Array()
    for (i = 0; i < p; i++){
    preBuffer[i] = new Image()
    preBuffer[i].src = theImages[i]
    }
    var whichImage = Math.round(Math.random()*(p-1));
    function showImage(){
    document.write('<img src="'+theImages[whichImage]+'">');
    }
    </script>
    </head>

    <body>
    <script language="javascript">
    showImage();
    </script>

    create a new function in the head of your file:

    function randOrd(){
    return (Math.round(Math.random())-0.5); }

    then insert this right below where you defined the array,

    theImages.sort (randOrd);
