Well that's not what the documentation says now.  It just says you

I could run a mysql database but it seems a little OTT for what I
actually want to do.

They should be the same, same disk drive, same directory structure.

Surely it's not an unusual requirement, allow manipulation of the same
hierarchy of pictures from more than one place.
