If she models and has photographs taken of her - well, they're going to be posted somewhere publicly anyway so why not show the people you have as a friend? There's nothing wrong with that at all.

And, as she is NOT currently a therapist, psychologist, or counsellor of any sort, there's absolutely nothing at all wrong about her posting photos like that. It doesn't even reflect what she plans to do with her page if she does pursue the PhD. For all you know, she might plan on making things private once she begins a practice. Or make her name unsearchable, or have a pseudonym online. You can't read her mind or know her plans.

There's absolutely nothing wrong with her, and while it may not be to your tastes, it's absolutely disrespectful to say that she had to have been dropped on her head!

I'm not sure if you wanted to just be friends with her or if you were interesting in pursuing a relationship with her, but she's still the same person that you were already getting to know. She just also has a high degree of confidence in her body and ability to handle sexualized comments directed at it.
