If you use KDE, putting an image on the root window won't do you much
good, for if you change your desktop and back again, it will be
overwritten with the old background. However, you can exploit this
feature, define a background image in KDE and overwrite this image
file from IDL. I do this to load "current" (i.e. today's) satellite
images on my background. Only that I barely ever see them because of
all these open windows. Time for a 64" monitor ;-)
Cheers,
Martin
