title: Get larger facebook image through firebase login
body: <p>I am using firebase to login a user through facebook. This all works fine and I can get the users FB profile image, although it is to small. Can somebody tell me how to get a larger one, the code I am using:</p>
  
  <pre><code>     override func viewDidLoad() {
              let loginButton = FBSDKLoginButton()
              loginButton.readPermissions = ["public_profile", "email"]
              loginButton.delegate = self
              self.view.addSubview(loginButton) 
          }
  
  func loginButton(loginButton: FBSDKLoginButton!, didCompleteWithResult result: FBSDKLoginManagerLoginResult!, error: NSError?) {
  
          let credential = FIRFacebookAuthProvider.credentialWithAccessToken(FBSDKAccessToken.currentAccessToken().tokenString)
  
              FIRAuth.auth()?.signInWithCredential(credential) { (user, error) in
                  if let user = FIRAuth.auth()?.currentUser {
                  for profile in user.providerData {
                  let photoUrl = profile.photoURL?.absoluteString //SMALL IMAGE
                     }
                  }
              }
          }
  </code></pre>
  
  <p>(This is done in swift)</p>
