I appreciate the FindAGrave work that volunteers do--it was so comforting to find pictures of headstones of relatives online. But I can see how your sister considered an unauthorized photo to be an invasion of privacy. Hmmm, I'm wondering about the legality of that? Are dead people in the public domain? I guess if your sister felt really strongly about it and they refused to take it down, she'd have to take the website to court, which of course it would never come to.
