Newbee, what do you mean with your comment?
Surely you don’t mean that now that it’s widespread, it’s okay – that doesn’t make sense. If halachic dinners became the norm, would that make them okay? 😉
If you mean that the chosson/kallah shouldn’t pose in a way they’d be uncomfortable being posted online, then yes, but they shouldn’t be doing that anyway.
If you mean that they shouldn’t put effort into controlling the release of pictures online, I still disagree. I know people who did that successfully, although, perhaps that’s easier in my circles, where online pictures of simchas aren’t really the norm.
