Thirdly, can we post any picture, or do we have to have specific permissions?
Thanks for your help

After a while, these become "public domain," and if no one has complained about them in the amount of time they have been around, then they are probably OK to put up.

This is not correct. It depends heavily on the juristication you are under. And just because "it has been around so long" and "no one got caught" this doesnt mean it's legal.
Usually, people who publish pics somewhere do this for a reason. And I think it's only fair to respect this reason. So, if the owner wants to share it- fine. But if he doesnt, that should be respected.
So, if it's not yours, and you don't know the owner (or his view on things getting posted elsewhere) dont post it
