title: Icon is not displayed on the chat window of QnA Bot
body: <p>I have tested the Microsoft QnA Bot with a positive restult. Everything works fine as expected. I can see next to a message the name of the sending entity. Next to the message I was expecting to see an image, however in my case I do not see it.</p>
  
  <ol>
  <li>I have uploaded an icon on my service on  <a href="https://qnamaker.ai/" rel="nofollow noreferrer">https://qnamaker.ai/</a></li>
  <li>I have also uploaded one on the <a href="https://dev.botframework.com/" rel="nofollow noreferrer">https://dev.botframework.com/</a>
  Uploading the icons I was aware of the size 50px x 50px.</li>
  <li>On the test on dev.botframework.com/ the icon was also not displayed.</li>
  </ol>
  
  <p>I havent found any other suitable answer online.
  Does anyone have a recommendation?</p>
  
  <p>Thanks a lot!</p>
