OK, there are two main issues with your code.

FIRST:

Remove session_destroy() from your code. It's the reason why the session is being deleted. You can then remove the second use of $session = new FacebookSession( $_SESSION['fb_token']); from your code. You only need to do that bit once!

$request = new FacebookRequest(
  $session,
  'POST',
  '/me/photos',
  array (
    'source' => new CURLFile( $location.$name ),
  )
);
