title: UIDocumentInteractionController works but doesn't show "Save Image"
body: <p>I create and present a <code>UIDocumentInteractionController</code> with a valid url to a saved image but when I present the controller "Save Image" does not appear. </p>
  
  <pre><code>NSURL *url = ...;
  self.interactionController = [UIDocumentInteractionController interactionControllerWithURL:url];
  [self.interactionController presentOptionsMenuFromBarButtonItem:sender animated:YES];
  </code></pre>
  
  <p>I have verified <code>self.interactionController.UTI</code> is a valid image type (jpeg) </p>
