title: force download of different files
body: <p>I am trying to force a php download. from here:
  <a href="http://www.iwantanimage.com/animals/animals01.html" rel="nofollow">http://www.iwantanimage.com/animals/animals01.html</a>. Click on the sterling image &amp; the next page offers the options of three formats.</p>
  
  <p>this is my php code</p>
  
  <pre><code>&lt;?php
  header('Content-disposition: attachment; filename=sterling02md.jpg');
  header('Content-type: image.jpg');
  readfile('sterling02md.jpg');
  
  header('Content-disposition: attachment; filename=sterling02lg.jpg');
  header('Content-type: image.jpg');
  readfile('sterling02lg.jpg');
  
  header('Content-disposition: attachment; filename=sterling.jpg');
  header('Content-type: image.jpg');
  readfile('sterling02.jpg');
  ?&gt; 
  </code></pre>
  
  <p>The only image that downloads however is the sterling02md.jpg. How do I fix the code so the user can download the file of choice?
  thank you</p>
