Everything seems fine except for one miniscule problem.  A mirror image of
the image map projected on the opposite side of the object.  How do I
counteract this?

The usual approaches are two.

1. Split the object in two, apply the image map to one half, glue them
back together

2. Use a proper textur_map to constrain the image map. With a planar
map type a planar pattern works best, and a radial pattern is usually
used with the other map types (I am not considering UV mapping, mind
you).

Hope this helps.
