Hi,

Sorry for the late reply, I've been out of touch for a while.

You might look at www.atlasmd.com

We use it as an image management tool, and have no problems. We funded the port
to PostGIS & it uses mapserver/javascript, with image locations as points in
the internal db, manages images in directories with paths in the db. We have
abstracted all the background layers to our corporate WMS server, so they are
not managed on the atlas server.

It is s commercial tool, sitting on top of Firebird or PostGIS.... which may
not be what you are after, but the developers are very competent & helpful & it
is pretty customisable.


Cheers,
