(I really do have a penchant for intellectual titles, don't I? ;)
Anyway... having been nudged back into coding I've got the "friends groups" on
IPP sorted - this means I can now move on to set up photo albums (I've shifted my priorities on this one a bit). After which (and when I've done some security testing) I'll be able to put most of my pics online, with appropriate access control.
And now I'm going to sleep.
