I made an attempt at this tonight, as sleep still
eludes me. :-(

I put the Coyote Graphics file here:

http://www.idlcoyote.com/misc/cg_geotiff_image.pro

And I put an attempt at a Function Graphics file
here:

http://www.idlcoyote.com/misc/ng_geotiff_image.pro

I cannot size the image appropriately, or even leave
room in the window for the title. If someone could
make it work, I would be *extremely* grateful. :-)

Going to bed now. :-)

Cheers,

David
