Did this ever get resolved?  I recently wanted to do exactly this:
open an image on a networked machine under XP and had the same problem
(version 3.6).  Also I note that when you get a file list, network
shares (even mapped drives) do not appear.  As Ned noted you can open
network paths without much trouble.  Any updates?  Thanks.
