title: Curtail UIImage download size from WEB
body: <p>I have an application that downloads images based on URL using the call: </p>
  
  <pre><code>img = [[UIImage alloc] initWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:urlToImage] options:0 error:&amp;err]];
  </code></pre>
  
  <p>where URL is an image on the WEB.</p>
  
  <p>I really want to curtail the amount of data transfer, so would like to reduce the file size of the download.</p>
  
  <p>I was wondering if anyone has a magic way of reducing the file size of the download short of implementing a PHP server process to be the go between to take care of this.</p>
  
  <p>Thanks in advance!</p>
