Skip product-page and goto big image

We're using PC (Just installed by IE) as a catalog (not as cart) and I like to accomplish the following....

When I view a category, products are listed...
When you click on the image, it goes to the product-page.
On the product-page, you have the image you can click on, that will show you the large image via the (javascript) Zoom function.

What I like to do, is on the category-page, when you click on the image, it's not going to the product-page, but shows this Zoom-function from here. (Not to confuse with the Ajax tool-tip!)

I know that the link ( pcStrPrdLink ) on the category-page on this image, comes out the file pcShowProductH.asp at line 23, and think this needs to be changed -->

%if pSmallImageUrl<>"" then%>              <p><a href="<%=pcStrPrdLink%>" <%if scStoreUseToolTip="1" or scStoreUseToolTip="2" then%>onmouseover="javascript:document.getPrd.idproduct.value='<%=pIdProduct%>'; sav_callxml='1'; return runXML1('prd_<%=pIdProduct%>');" onmouseout="javascript: sav_callxml=''; hidetip();"<%end if%>><img src="catalog/<%response.write pSmallImageUrl%>" alt="<%=pDescription%>"></a></p>         <% else %>             <p><a href="<%=pcStrPrdLink%>" <%if scStoreUseToolTip="1" or scStoreUseToolTip="2" then%>onmouseover="javascript:document.getPrd.idproduct.value='<%=pIdProduct%>'; sav_callxml='1'; return runXML1('prd_<%=pIdProduct%>');" onmouseout="javascript: sav_callxml=''; hidetip();"<%end if%>><img src="catalog/no_image.gif" width="50" height="50" alt="<%=pDescription%>"></a></p>         <%end if %>

The question is:
How to accomplish this?  I have tried to figure out what to use to replace the link, but have not been able to succeed yet.

To help out, I created a shot of how I like it to be.... This shot represents the Category-page.
(Of cos. this is quickly thrown together with test-products and a test-category)



Anyone can help me (a newb. ASP guy) out on this?
Thanks!

ps.:
Using Prod.Cart V4.1 SP1 (no apparell addon, etc..)
