OK. Point taken. Did not know that and will rewrite my script.
This does not help with the DISPLAY part.

When I use the following in a script I get the error below:

DISPLAY=:0.0 xfconf-query -c xfce4-desktop -p /backdrop/screen0/monitor0/image-path -s $PIC2

** (process:4727): CRITICAL **: Failed to init libxfconf: /bin/dbus-launch

Theologians can pursuade themselves of anything. Anyone who can worship
a trinity and insists that his religion is a monotheism can believe
anything -- just give him time to rationalize it.
