title: HTMLPurifier Breaking Images
body: <p>I'm trying to run HTMLPurifier on user input from a WYSIWYG (CK Editor) and the images are breaking.</p>
  
  <p>Unfiltered Input:</p>
  
  <pre><code>&lt;img alt="laugh" src="/lib/ckeditor/plugins/smiley/images/teeth_smile.gif" title="laugh"&gt;
  </code></pre>
  
  <p>After running through purifier with default settings:</p>
  
  <pre><code>&lt;img alt="&amp;quot;laugh&amp;quot;" src="%5C" title="&amp;quot;laugh&amp;quot;"&gt;
  </code></pre>
  
  <p>I have tried changing the configuration settings; but I the src is never preserved.  Any thoughts?</p>
