title: including facebook.php makes my web shows extra information
body: <p>I have read some tutorials related to displaying Facebook name, picture and so on.
  To do that I must include (or require) the file "Facebook.php", which I downloaded in latest version from Facebook github web.
  The problem is that when I require "facebook.php" my web looks like this:
  <a href="http://imageshack.us/f/543/facebookphp.png/" rel="nofollow">http://imageshack.us/f/543/facebookphp.png/</a>
  The file is supposed to contain functions like getUser() and the Facebook instance, for example, but why has it got all that html code that appear in my web?</p>
