> First, for XAUTHORITY should be: XAUTHORITY=/var/run/xauth/A${DISPLAY}-*
This works:
DISPLAY=:0 XAUTHORITY=/var/run/xauth/A${DISPLAY}-msFdGa import -window root iitdm.png
These do not
DISPLAY=:0 XAUTHORITY=/var/run/xauth/A${DISPLAY}-* import -window root iitdm.png
DISPLAY=:0 XAUTHORITY=/var/run/xauth/A${DISPLAY}* import -window root iitdm.png
Of course, the one that does work requires lookup of the content of /var/run/xauth/ after a reboot.

I don't know why the URL I was working from used xwd instead of import.
Another URL that fails to provide a way that works, it too is for gdm:

Search on kde.org only found shooting desktop with Spectacle, not greeter.
