Sam2, that’s what I see from where I come from. I understand were human beings and davka because that we shouldn’t have pictures of women online. Maybe you will get happy to see the smiling kallah and chassan, but that picture may excite others in a different way.
Plus a kallah belongs to her chosson. I don’t know…it’s just not good to posting pictures online at all in my opinion.
You should not be sending pictures to friends either (unless perhaps you belong to your friends?). In fact, you should not be taking digital pictures at all. Haven’t we learned anything from the Dor Yeshorim video?
Once it is out of your hands, anything can happen, and you will have no one to blame but yourself.
