You need to start a new render loop (to avoid that the parent page is
displayed within the frame) and display some component. Try to add the
following code at the end of the method #image:

  WARenderLoop new
      show: (WAComponent new
           addMessage: 'File successfully uploaded';
      withToolFrame: false

Replace the expression within brackets with your own component that
displays the confirmation.
