title: How to fetch a profile picture of a Google Plus account?
body: <p>I'm kind of building a website and I want to allow Google login. I don't want my customers upload their profile pictures again to my website.  I have some clue on how to do it with facebook, but how do I fetch a profile picture from a google plus account once the user has been authenticated via a Google account?
  Is there any API for this? If yes, kindly share. </p>
