The only trick here is to get the javascript to include the "dynamic"
URL;  everything else is not specific to Zope or ZPT.  Here is the hack
I usually use for that::

  <!-- assumes that 'image' is bound to an actual Zope image object -->
  <script type="text/javascript" lang="JavaScript"
          tal:define="img_url image/absolute_url"
          tal:content="string:var img_url='${img_url}';"></script>

Your popup javascript can then refer to the 'img_url' JS variable to set
the window location.
