You were very close -- the trick here is that 'objectValues' returns
real objects, not IDs.  Try this (untested)::

  <dtml-in "objectValues( [ 'Photo' ] )">
   <dtml-let photo=sequence-item> <!-- alias so we can use in expr! -->
    <dtml-var "photo( display='thumbnail' )">
   </dtml-let>
  </dtml-in>
