title: Get binary image data from PIL.Image?
body: <p>I've opened an image in PIL like so:</p>
  
  <pre><code>from PIL import Image
  
  i = Image.open("image.jpg")
  </code></pre>
  
  <p>I need to access the raw contents of this file. How can I get the entire picture data, as if I would have done <code>open(...).read()</code>?</p>
