Help with AS2 - photo gallery

Question

Hi All
would someone beable to help me with some code, I downloaded a photo gallery example, at the moment the movie plays the photos when you click a button(timer)
What I'm trying to do is to get the movie to auto play the photos on load rather than having to click the button. I have been lookin in the scrip, I think its something to do with
// initialize values
  currentIndex = 0;
but when I change this value to 1, not much happens, would some be able to have a look within the code and see where I can change it so that the movie runs the images automatcally on load.
I have pasted the code below, hope this is ok?
many thanks for anyones help!

fscommand("allowscale", "false");
Stage.scaleMode = "noScale";
targetPhoto._visible = false;
slides_xml = new XML();
slides_xml.onLoad = loadSlideShow;
slides_xml.load("album.xml");
slides_xml.ignoreWhite = true;
function loadSlideShow(success) {
if (success == true) {
  rootNode = slides_xml.firstChild;
  totalSlides = rootNode.childNodes.length;
  currentSlideNode = rootNode.firstChild;                            
  photos = new Array(totalSlides);
  thumbs = new Array(totalSlides);
  captions = new Array(totalSlides);  
  tx = 0;
  for (i=0; i < totalSlides; i++) { // populate arrays and create thumbnails dynamically
   photos[i] = currentSlideNode.attributes.jpegURL;
   thumbs[i] = [currentSlideNode.attributes.jpegWidth,currentSlideNode.attributes.jpegHeight];
   captions[i] = currentSlideNode.firstChild.nodeValue;
   _root.attachMovie("thumb","thumb"+i,i);
   _root["thumb"+i]._x = tx;
   _root["thumb"+i]._y = 595; // using fixed Y coord
   _root["thumb"+i].tindex = i;
   tx += 22;  
   currentSlideNode = currentSlideNode.nextSibling;
  // initialize values                      <<<<<<<<<<<<<<<<<<<<<<<IS IT HERE?????
  currentIndex = 0;
  targetWidth=thumbs[currentIndex][0]; // get width
  targetHeight=thumbs[currentIndex][1]; // get height;
  updateSlide();
function updateSlide() { // load photo, update caption and status fields
targetPhoto.loadPhoto(photos[currentIndex]);
caption = captions[currentIndex];
statusField = (currentIndex+1) + "/" + totalSlides;
function slideShow() {
if (currentIndex == totalSlides-1) { currentIndex = 0; } else { currentIndex++; }
targetPhoto._visible = false;
targetWidth=thumbs[currentIndex][0]; // get width
targetHeight=thumbs[currentIndex][1]; // get height;
updateSlide();
MovieClip.prototype.loadPhoto = function(fn) { // load external jpeg method + preloader
this.createEmptyMovieClip("holder", 1);
this.holder.loadMovie(fn);
this.onEnterFrame = function() { // NOTE: could use this to display percentage to user
  if (Math.floor((this.holder.getBytesLoaded()/this.holder.getBytesTotal())*100) >= 100) {
   delete this.onEnterFrame;

something like this...not quite working
function updateSlide() { // load photo, update caption and status fields
setTimeout(targetPhoto.loadPhoto(photos[currentIndex], 2000);
caption = captions[currentIndex];
statusField = (currentIndex+1) + "/" + totalSlides;
