Magento product image switcher

Recently had a client who wants to display the more views thumbnail in the main picture when clicked. Then when the main picture is clicked, the main picture will be displayed via lightbox.
For the Image switcher: (replace the catalog/product/view/media.phtml content with these)

<?php
    $_product = $this->getProduct();
    $_helper = $this->helper('catalog/output');
    $_gallery = $this->getGalleryImages();
    $_resize = 265;
?>

<style type="text/css">
.product-img-box .more-views li.slide-current a{ border:2px solid #aaa; }
.product-img-box .product-image-zoom img { cursor: pointer; }
#slide-loader{ visibility:hidden; position:absolute; top:auto; left:auto; right:2px; bottom:2px; width: 25px; height: 25px; }
</style>

<script type="text/javascript">
function slide(url,num,gallery){
  if (typeof slide.loading == 'undefined') slide.loading = false;
    if(slide.loading) return false;
      var loader = new Image();
      $(loader).observe('load', function(){
         $('slide-loader').setStyle({'visibility':'hidden'});
         $('div.more-views li').each(function(el,i){
           (i==num) ? el.addClassName('slide-current') : el.removeClassName('slide-current');
         });
         var dummy = new Element('img', { src: url }).setOpacity(0);
         new Insertion.After('image', dummy);
         new Effect.Opacity(dummy, { duration:.5, from:0, to:1.0 });
         new Effect.Opacity($('image'), { duration:.5, from:1.0, to:0, 
         afterFinish: function(){
        $('image').writeAttribute('src',url).setOpacity(1).observe('click',function(e){
  Event.stop(e);
  popWin(gallery, 'gallery', 'width=300,height=300,left=50,top=50,location=no,status=yes,scrollbars=yes,resizable=yes'); 
  return false;
;})
dummy.remove();
slide.loading = false;
}
});
});
$('slide-loader').setStyle({'visibility':'visible'});
loader.src=url;
slide.loading = true;
return false;
}
</script>

<p class="product-image-zoom">
<?php
$_img = '<img id="image" src="'.$this->helper('catalog/image')->init($_product, 'image')->resize($_resize).'" alt="'.$this->htmlEscape($this->getImageLabel()).'" title="'.$this->htmlEscape($this->getImageLabel()).'" onclick="popWin(\''.$this->getGalleryUrl().'.\', \'gallery\', \'width=300,height=300,left=50,top=50,location=no,status=yes,scrollbars=yes,resizable=yes\'); return false;" />';
echo $_helper->productAttribute($_product, $_img, 'image')
?>
<img id="slide-loader" src="<?php echo $this->getSkinUrl('images/opc-ajax-loader.gif') ?>" />
</p>
<p class="a-center" id="track_hint"><?php echo $this->__('Click on above image to view full picture') ?></p>
<?php if (count($_gallery) > 0): ?>
<div class="more-views">
<h4><?php echo $this->__('More Views') ?></h4>
<ul>
<?php foreach ($_gallery as $_image): ?>
<li>
<a href="<?php echo $this->helper('catalog/image')->init($this->getProduct(), 'image', $_image->getFile()); ?>" onclick="slide('<?php echo $this->helper('catalog/image')->init($this->getProduct(), 'image', $_image->getFile())->resize($_resize) ?>',<?php echo ($s = isset($s) ? ++$s : 0) ?>,'<?php echo $this->getGalleryUrl($_image) ?>'); return false;"><img src="<?php echo $this->helper('catalog/image')->init($this->getProduct(), 'thumbnail', $_image->getFile())->resize(56); ?>" alt="<?php echo $this->htmlEscape($_image->getLabel()) ?>" title="<?php echo $this->htmlEscape($_image->getLabel()) ?>" /></a>
</li>
<?php endforeach; ?>
</ul>
</div>
<?php endif; ?>

One thing to note though. When the main picture is clicked, it will load the image in a popup window which is not beautiful.. I want to add a lightbox effects that will load the main picture when clicked.

Update: achieved the thickbox lightbox integration. Refer to this site : www.room9.nl
Here's the same code from above but modified...

<?php
$_product = $this->getProduct();
$_helper = $this->helper('catalog/output');
$_gallery = $this->getGalleryImages();
$_resize = 350;
?>

<style type="text/css">
.product-img-box .more-views li.slide-current a{ border:2px solid #aaa; }
.product-img-box .product-image-zoom img { cursor: pointer; }
#slide-loader{ visibility:hidden; position:absolute; top:auto; left:auto; right:2px; bottom:2px; width: 25px; height: 25px; }
</style>

<script type="text/javascript">
function slide(url,num,gallery){
if (typeof slide.loading == 'undefined') slide.loading = false;
if(slide.loading) return false;
var loader = new Image();
$(loader).observe('load', function(){
$('slide-loader').setStyle({'visibility':'hidden'});
$('div.more-views li').each(function(el,i){
(i==num) ? el.addClassName('slide-current') : el.removeClassName('slide-current');
});
var dummy = new Element('img', { src: url }).setOpacity(0);
new Insertion.After('image', dummy);
new Effect.Opacity(dummy, { duration:.5, from:0, to:1.0 });
new Effect.Opacity($('image'), { duration:.5, from:1.0, to:0, 
afterFinish: function(){
$('image').writeAttribute('src',url).setOpacity(1).observe('click',function(){
$('swapper').href = url;
})
dummy.remove();
slide.loading = false;
}
});
});
$('slide-loader').setStyle({'visibility':'visible'});
loader.src=url;
slide.loading = true;
return false;
}
</script>

<p class="product-image-zoom">
<?php
$_img_a = '<a id="swapper" class="thickbox" rel="group" href="'.$this->helper('catalog/image')->init($_product, 'image').'" title="'.$this->htmlEscape($this->getImageLabel()).'">';
$_img_b = '<img id="image" src="'.$this->helper('catalog/image')->init($_product, 'image').'" alt="'.$this->htmlEscape($this->getImageLabel()).'" title="'.$this->htmlEscape($this->getImageLabel()).'" /></a>';
?>
<?php echo $_helper->productAttribute($_product, $_img_a.$_img_b, 'image') ?>
<img id="slide-loader" src="<?php echo $this->getSkinUrl('images/lightbox/loading.gif') ?>" />
  </p>
<?php if (count($_gallery) > 0): ?>
<div class="more-views">
<h4><?php echo $this->__('More Views') ?></h4>
<ul>
<?php foreach ($_gallery as $_image): ?>

</li>
<?php endforeach; ?>
</ul>
</div>
<?php endif; ?>
