title: Saving an animated GIF in Pillow
body: <p>(Python 3.4, PIL 1.1.7, Pillow 2.5.1)</p>
  
  <p>I expected this to copy the original GIF.</p>
  
  <pre><code>from PIL import Image
  im = Image.open(filename)
  im.save('temp.gif')
  </code></pre>
  
  <p>Instead, it saves the first frame as a still.</p>
  
  <p>What am I doing wrong?</p>
