title: facebook application needs dimensions of profile picture
body: <p>I am using the server flow facebook application and when I get the user's profile picture, I save that URL in my HttpSession.  However, I also have a javascript feature that when mousing over certain posts in my application, and my user is a facebook user, I show the picture at about 100 pixels size.  However, I don't know the relative height/width ratio of the picture, and it is framed in a box.  I need to know the height and width of the facebook picture that was uploaded by the user, but I can't find this information in the facebook developer graph api.</p>
