mazal77: I cannot use a photograph of you for financial gain without your permission. I can take it, though.
This gets to a much deeper issue, though. That being, what are the Halachic rights to privacy in the public sphere? And is a wedding a public sphere? I don’t have answers to these off the top of my head. Lich’ora, there is no right to privacy in public. That being said, Lashon Hara is always an issue. Of course, it’s hard to see what Lashon Hara there is in someone getting married. And if it’s considered not normal to not want people to know you got married (I said if, I have no idea if it is), I don’t think someone has a right to claim they feel uncomfortable by it. I don’t know what is considered normal by posting a wedding picture either.
