On next.tiki.org i got an error about the Images field now being disabled by default as we should all be using Files fields, so a briefly enabled tracker_change_field_type pref and changed that field over (having checked there wasn't any images stored in them first, of course).
So now we just need some pictures in them! 😊
While i was there i also updated the fields permanent names (they were f_xx type ones from the old days) and set some options and names better while i was there.
Hope TikiFest Timeline still works (looks ok to me)!
