title: Assign img' src dynamically
body: <p>The page will display an image's url text correctly.  But I am not sure how to assign the message to the img 's src to display the image.</p>
  
  <pre><code>&lt;DIV class="msgStyle1" id="message"&gt;Waiting for image&lt;/DIV&gt;
  &lt;div class="imgStyle1" id="message"&gt;
      &lt;img src=whatneedtogohere /&gt;&lt;/div&gt;
  
  
    function displayText(text) {
      console.log(text);
      document.getElementById("message").innerHTML=text;
      window.castReceiverManager.setApplicationState(text);
    };
  </code></pre>
