Larger image link opens image in same window.

Hi everyone

I have tried figuring this one out but so far no luck. All the " Click here for larger image" links work fine except for a new product i have put under product type -free shipping. All the other products so far are under "product type general".
When you click the link for Larger Image it opens the image in the same window.

I am using the Zen Lightbox mod with success so i dont think it has anything to do with this.
This is the first time its happened and it only happened when i decided to use the product type "free shipping" for this particular type of product.

Can any of you wise owls out there please help me?

Heres the Link

Thank you

Looks like you have commented out the ability to have the large image:

<!--bof Main Product Image -->

<div id="productMainImage" class="centeredContent back">
  <!-- begin zen lightbox v1.3 aclarke 2006-10-20 -->
  <script language="javascript" type="text/javascript"><!--
document.write('<a href="images/rest_assured/standrews.jpg" rel="lightbox[gallery]" title="Rest Assured - St Andrews - Premiur Universal."><img src="bmz_cache/8/80fc9f92a600ee77a874d4451c7c4f8c.image.300x200.jpg" alt="Rest Assured - St Andrews - Premiur Universal." title=" Rest Assured - St Andrews - Premiur Universal.

It also looks like you have an add-on ...

Perhaps you do not have the add-on installed correctly?

Thanks for replying Linda

Still no joy here.
I checked out the code on one of my other products in the product_general section and it seems to be the same( comment code in the same place), every things works fine.
The only differance i can see is that the hyperlink referance points to the bmz_cache folder and not to to folder where the image is located..

I tried this on a fresh install as well...same problem.

Thanks
