i cant randomize image . suggestion on doing wrong :)

you should "randomize" array:

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

and paste function in code: https://stackoverflow.com/a/2450976/3132718
