I would think it should be covered by the same doctrine.
Just as an exercise. Suppose a private club is where all members are know to the owner and all associate members are know to a member. A public square is a place where people can stumble into without any direct affiliation (search, directory, discovery, recommendations, shares).
Under this definition it matters not who is hosting your pictures, it only matters if strangers are welcome. And if they are then all strangers are welcome.
Now my idea here does cover the hypothetical theater - you want people to discover it, but you don’t want them causing noise during the performance. So it’s not a great definition. But it serves to illustrate.
