title: Automatic inclusion of @2x images (retina support)
body: <p>Can any one tell me code of auto including @2x images if device is switched to iphone 4.
  I have searched very far on it, but nothing fruitful is found yet.</p>
  
  <p>I have already included @2x images in my resource file. I want code to write so that images resize and reposition them selves when application is running on iphone 4.</p>
