title: UIImage initWithContentsOfFile doesn't work
body: <p>I have question: I want to avoid [UIImage imageNamed:].
  So i did:</p>
  
  <pre><code>UIImage *prodImg = [[UIImage alloc] initWithContentsOfFile:@"myimage.png"]; 
  controller.productImg.image = prodImg;  
  [prodImg release];
  </code></pre>
  
  <p>But now the image is not shown anymore.</p>
  
  <p>Does anyone know how to get that to work?</p>
