OK, so the colors are "wrong" but it does display images with gnuplot
and allows plotting 2-d data over the images, doesn't it?

I think the problem is that we are always applying a colormap but we
shouldn't.
The other day, I asked:
Is there some information that shows up in the graphics handle
properties, or is this choice made when the data is displayed?
and received no reply. See
https://www.cae.wisc.edu/pipermail/octave-maintainers/2007-February/001797.html
When someone can help a little with how this should be implemented, I
can maybe do something about it. If there is some information stored
in the graphics properties, what is it?
