title: RAILS - paperclip don't work with Ajax
body: <p>i have an application working fine with form_for updloading an image using paperclip.</p>
  
  <p>The problem is, because of the javascript security model, it cannot upload a picture via AJAX.</p>
  
  <p>I would like to know: what is the best approach, that really works with rails 2.3.x, to send file via aJAX using rails? IFRAME technique? swfupload? Any other idea?</p>
  
  <p>VP</p>
