Got one of those friends who constantly floods Facebook with photos? Like, you haven't talked to her since high school, but you've seen 8,000 pictures of every vacation she's taken in the past five years?

Yeah…she's got self-esteem issues.

According to a new study from the University of Buffalo, women who base their self-worth and self-esteem on their appearance share more photos online...and have more Facebook friends...than women who are more secure.

They didn't find the same connection with men.
