[Zope] Question about accessing properties of images

[Kevin Carlson]

The Key error occurs on pic.desc.  In other words:

<dtml-var pic.desc> fails with an error on 'pic.desc'.

<dtml-var expr="pic.desc"> returns an attribute error on 'desc' which is a
valid property that I have entered for the 'pic' object.

This works:

     <dtml-in objectItems prefix=p >
         <dtml-if expr="p_key == pic">
             <dtml-var desc html_quote>
         </dtml-if>
     </dtml-in>

Just seems like a performance waste to loop through the objectItems when I
have the key available.  Any other ideas?
