That means no-one knew the answer, or no-one has read it yet that does.

Yes.  It also supports images as long as they have associated ".geo"
files and you have compiled in ImageMagick (most image formats) or
XPM (XPM format images).

That script is set up for particular file naming common for USGS
geoTIFF topo map files.

You don't need to go through all that.

Instead, keep it as a regular TIFF file, create a .geo file to go
with it, and use it!  Check out the online help (as in the help menu
inside Xastir itself) for the .geo format.  They're easy!
