Firstly, the article is not talking about taking pictures of women on the street but rather in changing rooms and locker rooms, which is a crime. Second, even if you would be comfortable if someone took a picture of you naked without your knowledge and posted it online doesn't mean that other women and men are.
"Is it ok for the same woman to appear in both these news?"
Yes. It was her decision to pose topless in public, and it doesn't give anyone the right to spy on her in privacy and take pictures of her.
