Cynthia, thanks. If that's correct though it's a bit odd because you can still select the corresponding check boxes if you go back into the edit page. Also, if you'd like to link an image retrospectively (say you forgot when you first posted it) then you would have to delete the image completely and start again from scratch to get the FB link to work.
Surely that can't be right. Anyone from the FAA admin side like to chip in on this one?
