  <p>The problem is the <code>https://fbexternal-a.akamaihd.net/safe_image.php?d=AQCMr5crfpv0x3lm&amp;w=130&amp;h=130&amp;url=http\u00253A\u00252F\u00252Fi3.ytimg.com\u00252Fvi\u00252FRJer7-eAy3o\u00252Fmqdefault.jpg</code> part. </p>
  
  <p>If I visit <a href="http://i3.ytimg.com/u00252Fvi/RJer7-eAy3o/mqdefault.jpg" rel="nofollow noreferrer">http://i3.ytimg.com/u00252Fvi/RJer7-eAy3o/mqdefault.jpg</a> it shows the correct image, so that can't be the problem. Am I doing something wrong or is the <code>safe_image.php</code> just buggy and should I just strip the url to it's original url and use that?</p>
  
  <p>Tnx and greets,
  Sjaak</p>
