title: Kivy Image / Remove Image
body: <p>Regarding a Kivy Image widget.  I can't seem to figure out how to remove the source to make it blank.</p>
  
  <p>For example :</p>
  
  <pre><code>kivy_image_widget.source = None
  </code></pre>
  
  <p>I would like to clear the contents of an image widget when there is no data to display.</p>
  
  <p>Thanks,
  Dan</p>
