If you could elaborate a bit about what happens in each step, it would 
be a great learning experience.
and how to stop the sqlite session? could not think of something else 
than control c.
Don´t worry, I use a copy.

I have something similar at hand at the moment, wrestling with the setup 
from virtual box, it refuses to read from existing database.
I pointed in digikamrc to the place where db exist, in my normal setup 
db works with my pictures in the path /media/FOTO/FOTO/ARCHIEF/
but it kept stubbornly saying: path FOTO/ARCHIEF/ not found, so it looks 
like it uses a reletive path and doesn know about the base media/FOTO 
(which is the mounted drive called ¨FOTO¨.)
any ideas?

Best regards,
Rinus
