title: After upload, image thumbnail not displaying
body: <p>My dropzone js is not showing image preview after the upload.<br>
  My js code is:</p>
  
  <pre><code>$(document).ready(function() {
          Dropzone.autoDiscover = false;
          Dropzone.options.myDropzone = {
              maxFiles: 5,
              createImageThumbnails: true,
              acceptedFiles: ".jpeg,.jpg,.png,.gif",
              uploadMultiple: true,
              init: function() {
                  this.on("addedfile", function(file) {});
              }
          };
  </code></pre>
  
  <p>Also,I have changed css for the preview path (if that's the case), still no luck.<br>
  Please help.</p>
