Jim,

To clear up a point up front, you refer to stereograms. This
term is often used to refer to "Magic Eye" type pictures. If 
this is what you mean, you have to have special programs to 
produce them. They were all the rage a couple of years ago
and I think there is still some shareware out there for doing
them. You can not view magic eye pictures in the cross-eyed
mode unless they were especially disigned for it.

The term stereograph is often used to refer to twin pictures
(slide or print) that present a photographic scene. If the
left and right pictures are reversed, you view them in the
cross-eyed mode. If they are normally mounted, you view them
in the parallel or wall-eyed mode. Cross-eyed viewing is done
without a viewer. You can look at normal stereo pictures with
any number of different kinds of viewers depending on the 
format; slides, prints, etc. There are even viewers for looking
at prints in the over-under mode. There are several programs
for creating stereo pairs on the computer but if you produce
view cards or slides, no program is necessary.
