ZPhotoAlbum will be its own ZCatalog. If you want to search it by 
itself you can, or you can select multiple ZCatalogs to search.
This should be what you want, let me know otherwise.

Sure. I can see that. Try this.
<dtml-in "objectValues('Photo')">
  <dtml-var "tag(REQUEST, pdcookie='1', border=0)">
</dtml-in>

Let me know right away if this does not work.

This came up on the list last night. Try this.

<dtml-with "_.getitem(topimage,0)">
  # Return a reference to the Photo object that is named in topimage
  # Place the Photo on top of the namespace stack
  <dtml-var "tag(display='thumbnail', border=0)"> 
  # Call the tag method of the current object with parameters.
  # The REQUEST variable isn't necessary because we only want thumbnails.
  # Note that the alt tag defaults to the title
  # Further note that the /thumbnail method-interface is deprecated, all
  # displays are set through the display parameter.
</dtml-with>

I am open to suggestions on making this dtml-interface better, but
I found this to be the most flexible so far. It also reads more like
Zope code, but it takes a little getting used to. I may still have
much to learn here.
