Then they might be good enough to show a slide in the panoramic mount
(23x52) if someone were using just that format...  and it'd be closer
to "ortho" at 50mm (vs 28mm for a Horizon 202 camera taking lens).

Just a thought - I've been intrigued by panoramic 3D possibilities
for a while, but making a viewer that can handle 50+mm wide images
at near ortho is tough...
