title: Django Form with preview and confirmation
body: <p>Disclaimer: I'm a beginner at Django.</p>
  
  <p>I'm trying to create an app where I want the customer to preview and confirm a form before submitting it. I tried using the built-in Django FormPreview, but discovered that it didn't support File fields, so I threw it away.</p>
  
  <p>Could anyone point me in the right direction?</p>
