title: plupload2 image preview
body: <p>I am implementing a custom plupload uploader and wanted to include image previews before the image is uploaded to the server. How do I access the file? I plan to do this at the FilesAdded event as shown in the code snippet below:</p>
  
  <pre><code>uploader.bind('FilesAdded',function(up,files){
  $('#filelist').append('&lt;img src=" "/&gt;'); //render image preview here
  }
  </code></pre>
  
  <p>I am currently able to display other information such as image filename, size, etc. However, I don't know about the image preview.</p>
