title: NSData from Shorted URL not make UIImage
body: <p>I am facing problem with downloading a .jpg image using a shorted URL like this one:</p>
  
  <p>shorted URL:-  <a href="https://db.tt/KH5NgfT1" rel="nofollow">https://db.tt/KH5NgfT1</a> </p>
  
  <p>I got successfully <code>NSData</code> length of 41791 bytes. But problem is when I convert this NSData to UIImage it gives NULL and when this NULL image I am posting on faceBook It successfully posted to my facebook account, for post on facebook I am using <code>SLComposeViewController</code> and one thing more that is this Image is also not shown in <code>SLComposeViewController</code>.</p>
  
  <p>I am using this code for download image </p>
  
  <pre><code>NSData *downloadedImageData=[NSData dataWithContentsOfURL:[NSURL URLWithString:shortedURL]];
  </code></pre>
  
  <p>Convert to UIImage</p>
  
  <pre><code>UIImage *image=[UIImage imageWithData:downloadedImageData];
  </code></pre>
  
  <p>returns NULL image</p>
  
  <p>and My <code>SLComposeViewController</code> look like this</p>
