I have a html page of 9 images which must change their order when page is reloaded I have placed image as 3 rows and 3 columns which on reload should change the order of the image .

        var len = document.images.length;
        var images = document.images;
        var img = function (){
            for(var j, x, i = images.length; i; j = parseInt(Math.random() * i), x = images[--i], images[i] = images[j], images[j] = x);

            }
        window.onload = function(){
            for(var i = 0 ; i < len ; i++)
            {
                images[i].src = img[i].src;

    </script>
</head>

<body>

    <table>

You should "randomize" your array:

<script type="text/javascript">
    var len = document.images.length;
    var images = document.images;
    var img = function (){
        for(var j, x, i = images.length; i; j = parseInt(Math.random() * i), x = images[--i], images[i] = images[j], images[j] = x);
             }
    img = shuffle(img);//this "randomizes" the 'img' array using the function bellow
    window.onload = function(){
        for(var i = 0 ; i < len ; i++)
        {
            images[i].src = img[i].src;
        }

</script>

And paste this function in your code: https://stackoverflow.com/a/2450976/3132718
