So you'd be okay with a(n ex) partner posting intimate pictures and/or videos of you online for the whole world to see? Without you saying it's okay? Your face totally visible? Many wouldn't. It can be life-ruining.
Firstly, the copyright of the pictures is almost always likely to reside with the person taking the pictures who is often the one sharing them.
Secondly, in many/most jurisdictions many/most forms of copyright violation fall under civil, not criminal law. However, this is a criminal act and the penalty should be much higher.
Your girl/boyfriend takes a photo of you nude. Then they post it online without your consent. Are you okay with this?
In the case of photos of two or more copyright becomes even more inappropriate.
Given some of the news pieces about revenge porn, from both sides of the Atlantic, this seems a very sensible addition.
