I have Gallery running on Raspberry Pi (4B and Zero). I also set it up on Ubuntu 20.04. The documentation was a little fuzzy, but it works great on both.
Is there interest in a downloadable/flashable Raspian image file with working Raspberry Pi OS and Gallery3 server? Or would it be a waste of time? Would step-by-step instructions for terminal be more useful to more people?
Let me know what you think.
