Could someone please help me with some Js code?

Could someone please help me with some Js code?
I need to implement more than one gallery on a page, and the current script only allows one gallery.
Can someone please let me know if they can show me how to change the script to allow 10+ galleries on a page please?

Here’s a copy of the script:
<script type=“text/javascript” src=“jquery/jquery-1.4.1.js”></script>


<script type=“text/javascript”>
var currentImage;
var currentIndex = -1;
var interval;
function showImage(index){
if(index < $(‘.bigPic img’).length){
var indexImage = $(‘.bigPic img’)[index]
if(currentImage != indexImage ){
$(currentImage).fadeOut(500, function() {
myTimer = setTimeout(“false”, 3000);
$(indexImage).css({‘display’:‘block’, ‘opacity’:1});
currentImage = indexImage;
currentIndex = index;
$(‘.thumbs li’).removeClass(‘active’);
$($(‘.thumbs li’)[index]).addClass(‘active’);

function showNext(){
    var len = $('.bigPic img').length;
    var next = currentIndex &lt; (len-1) ? currentIndex + 1 : 0;

var myTimer;

$(document).ready(function() {
   myTimer = setTimeout("false()", 3000);
  showNext(); //loads first image
    $('.thumbs li').bind('click',function(e){
       var count = $(this).attr('rel');



And heres the url for the page:
Untitled Document

I would really appreciate someones help.
