Can we have it like others that the background changes every 10mins or what ever the user specifies?
Yes, you can e.g. install variety, or gnome extension bing wallpaper, gnome extension wallpaper switcher (this one only for Zorin 17, not 18), or shotwell.
I think variety is a good tool. It is very variable. You can install it with
sudo apt install variety
If you want to install a gnome extension, first install gnome extension manager, then open it and browse for the extension you want to install. For Zorin 17 select shell 43, for Zorin 18 shell 46.
Thanks will give it a try.
