It is a good idea, IMO, to use less than 800 pixels...
At a minimum, the browser's up/down scroll bar will
take up part of the 800 pixel screen width, making
it impossible to see 100% of both the left and right
image on the screen at the same time.

In addition to individual variations in freeviewing ability,
visitors' screen size will affect the total image size that
they are trying to fuse.

Seems on topic to me; anyone not interested just has to delete
or move on to the next digest message.

Tip #1: When displaying a triplet, store two files, one L and one
R.  Use an HTL page that displays R-L-R or L-R-L images inline.
A single jpeg of the entire triplet will be roughly 50% larger
file size.

Tip #2: Most people can crossview larger images than they can
parallel view (and cross viewing makes the 3D image look smaller).
The triplet is convenient, but probably not the best format.
Separate pages, with images sized appropriately for parallel or
cross viewing, are probably better.
