You can just store img_url as graph.facebook.com/FB_USER_ID/picture in database. In your webpages, you can simply use that URL like <img src="http://graph.facebook.com/FB_USER_ID/picture" /> to display the image.

You do not really need to know the "real" image URL. In-fact, that may eventually get defunct if user delets or changes his profile image. So, real image URL may not be advantageous. On the other hand, the symbolic URL provided by graph API will always point to the latest user image.
