Thanks for all the suggestions. I know how to get it working manually. I have built it with a clean install of Raspian and installed the app. That worked. The reason I wanted the image instead of the self install is that I want to switch between the 2 different apps to see which one I liked better. There doesn’t seem to be any instructions on how to build a duplicate of the disk image exactly the way it comes configured. Besides, if you want this to be adopted by people with different computer skills, the features built into Raspian should still all work.
Thanks,
Roger
