this is interesting. say someone accidentally sent a private picture of themselves to a group chat is it then illegal for someone in this group to share the picture a third party? likewise if someone accidentally sent a private picture to an individual is it then illegal for that individual to share the picture with a third party? edit: just noticed there is an intent requirement in the law as well.
