What does it mean when a girl cover her face in pictures?

imlikewtf
I checked out my crush's FB and she has a lot of pictures of her covering her face.. one of her friends there even commented something like ... "why would you post that, your covering your face" or "why would you even take picture, you're covering your face" and she's like " if I like it and I'm covering my face why not" (something like that)

I don't have a FB, just saw it using my friend's account, she's friends with him.
