In Germany we draw the line on what type of information the person in question makes public by their own choice. Do you invite tabloids for a home story and let them take pictures? Then other pictures of your home can be published. If you on the other hand never talk about your home and family publicly let alone invite media in, that can remain private. In addition, if the information is relevant to a larger topic (e.g. a corruption scandal involving a politician's home) then you can show anything relevant to that.
