I run a mind numbing series of init's to get this to work for me.
I currently use:

ScreenMaster:  This will load a copy of a graphic into memory and adjust
               the clut. Also provided is an init to reset the clut after
               the picture is desposed from the screen. (I leave this
               init out because I want the new clut to be remembered).
DeskPicture:   This will load the graphic again, but will retain it as
               the desk top picture.  If you have DeskPicture load in
               the same graphic that was previously loaded in by
               ScreenMaster, then the clut is already loaded (something
               that DeskPicture will not do)

ScreenMaster is ShareWare, and may do desktop pics sometime in the future.
DeskPicture, I believe is in the Public Domain.

I make the process more complex by having two minitors (one mono the other
colour) and wanted to have backdrops on both monitors.

Yes, this is possible.  The init to do so, called ColorDesk, by Paul
Mercer, is a comercial application and is available as part of the Screen
Gems package.  ColorDesk alows you to pick which monitor you want your
desktop pic to reside on (a choice that other cdev/init's do not give
you.. now if only it would do multiple monitors.. then I could throw away
all my other inits.. yeh!!.. hows about it Paul?)

     | Thanks...

Hope this helps.

Stu.

BTW, if I get inundated with requests to send ScreenMaster of DeskPicture
to people, I'll post it to the comp.binaries.mac.
