title: How to send an image in direct message?
body: <p>I'm trying to send an image in direct message using python + tweepy but no luck.
  It showed as a link in incoming messages.</p>
  
  <pre><code>imgurl = 'https://t.co/***'
  api.send_direct_message(screen_name='username',text=' '+imgurl)
  </code></pre>
  
  <p>Could you please advise?
  Official Twitter API doesn't shed a light for me as well.</p>
