What are you talking about exactly?
As far as I can tell if one wants to add frames to photographs Photoshop does have all the necessary functionality (and one could certainly automate such tasks).
sounds to me as though they are looking for pre-fab border effects.
Of course the requester is not accurate in saying you can't do it in Photoshop... I'm sure they mean there is no menu item automatic method.
In my opinion, this sort of difference between Photoshop and Elements is exactly what defines the products as either pro or consumer.
