How do get my image swatch to open to the original picture?

I'm currently using the code below to display my ubercart products images. It swaps the main image with the additional images when you click on them. The only problem is the main image doesn't open to a larger picture. How do I get this to open the original image? Thanks.

<?php
    </div>
    <div class="content-right">
      <?php if ($teaser) : ?>
        <?php print $node->content['image']['#value']; ?>
      <?php else : ?>
        <?php $num = count($field_image_cache); ?>
        <?php if ($num > 1) : ?>
          <div class="product-image">
            <div id="viewer" class="pics">
              <?php foreach($field_image_cache as $image) : ?>
                <?php print theme('imagecache', 'product', $image['filepath'], $title, $title); ?>
                <?php //print theme('imagefield_image_imagecache_thickbox', 'cart', $image, $image['filepath'], $title, $title); ?>
              <?php endforeach; ?>
            </div>
            <?php
              jquery_plugin_add('cycle');
              drupal_add_js('
                $(document).ready(function() {
                  $(\'#viewer\').after(\'<ul class="viewer-nav">\').cycle({ 
                    fx:     \'fade\',
                    speed:  \'slow\',
                    timeout: 0,
                    pager:  \'.viewer-nav\',
                    pagerAnchorBuilder: function(idx, slide) {   // callback fn that creates a thumbnail to use as pager anchor 
                      return \'<li><a href="#"><img src="\' + slide.src + \'" width="50" height="50" /></a></li>\'; 
                    }
                  });
                });',
                "inline"
              );
            ?>
          </div>
        <?php else : ?>
          <?php print $node->content['image']['#value']; ?>
        <?php endif; ?>
        <?
