To me, it looks like she really did have an accident, discover she would be ok then asked someone to take photos for Instagram. Which is a lot worse than staging it IMHO.
I was just imagining myself in her shoes and thinking that taking photos would be the last thing on my mind. I don't do blogging for a living so can't relate to her. I'm sure you're right. This is her life and she documents everything.
The problem is that people can't handle this, thus the demand and response is exaggerated.
