[Zope] random object with properties

[Kevin Worth]

I'm trying to find/write a method that will choose a random image 
from a folder (easy, using the random how-to)  But I also want to 
display the caption for the image, which is a property of that image.

This method:

<dtml-var expr="_.whrandom.choice(objectValues('Photo'))">
<dtml-if caption><dtml-var caption></dtml-if>

presents me with a random photo, but no caption.  At one point, I had 
it pulling out a random photo and a random caption, but I need the 
associated caption.

What am I missing here?
