I, too, am interested in scanning stereo slides, and I would like to
understand better what is involved.  When I picture scanning a slide in an
HP scanner, I envision inserting the slide in its mount from one end,
selecting the image in some kind of preview window and scanning it.  For the
opposite chip I would rotate the slide to the other end, select the image
again (which would be upside-down compared to the first chip) and scanning,
then rotating the chip 180 degrees so that both were right-side-up.  I
assume that the "windows" of the slide are square to the top and bottom
edges, so a rotation error is something I wouldn't expect.  Am I making a
bad assumption?

Also, what other problems would occur?

I've seen a lot of stereo photos on the web.  What successful practices are
used by those who post those photos?
