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:

#!/bin/bash
PIC2=$HOME/Pictures/to_work_on/wpm/rename_frist/02701_fadetoblue_1920x1200.jpg
DISPLAY=:0.0 xfconf-query -c xfce4-desktop -p /backdrop/screen0/monitor0/image-path -s $PIC2

Error:
** (process:4727): CRITICAL **: Failed to init libxfconf: /bin/dbus-launch
terminated abnormally
+with the following error: No protocol specified
Autolaunch error: X11 initialization failed
