[Zope] nested directories

[Matt Gregory]

If I have a namespace which contains a namespace called images while it's
parent also contains a namespace called images how do I make the following
section of code access the correct namespace?  I know where my obvious
problem is, when calling parent_meth from child_meth the parent_meth
dtml-with images is returning the child images object which does not contain
default.gif inside of it's namespace and therefore gives me an exception.
The question is what other options do I have?

in namespace like:
<parent>
   |_parent_meth (dtml_method)
   |_<images>
   |    |_default.gif
   |_<child>
         |_child_meth (dtml_method)
         |_<images>
              |_example.gif

****in child_meth****
<dtml-let image="'example.gif'">
    <dtml-var parent_meth>
</dtml-let>
<dtml-var parent_meth>

****in parent_meth****
<dtml-if image>
  <dtml-with images>
    <dtml-var images[image]>
  </dtml-with>
<dtml-else>
  <dtml-let image="'default.gif'">
    <dtml-with images>
      <dtml-var images[image]>
    </dtml-with>
  </dtml-let>
</dtml-if>
