title: JS file upload with PhantomJS/CasperJS
body: <p>I'm trying to automate uploading images in CasperJS.</p>
  
  <p>The form on the <a href="https://www.marktplaats.nl/syi/784/808/plaatsAdvertentie.html?bucket=221&amp;origin=HEADER" rel="nofollow">site</a> appears to be using plupload. Once a button is clicked, a file browser dialog appears where multiple images can be selected.</p>
  
  <p>How can I handle this file upload form with CasperJS? Is it possible to upload multiple images all at once?</p>
