Why images are not showing up in iframe? : <p>I am using iframe to show data from our media manager site. But iframe is not showing up images.</p>

<pre><code>&lt;!DOCTYPE html&gt;
  &lt;html lang="en"&gt;
&lt;head&gt;
   &lt;meta charset="UTF-8"&gt;
 &lt;title&gt;MM Test IFrame&lt;/title&gt;
&lt;/head&gt;
&lt;body&gt;
     &lt;iframe width="100%" height="400" src="http://mediamanager.b- 
     yy.com/filemanager/newmediamanager/filemanager/dialog.php" 
      frameborder="0" style="overflow: scroll; overflow-x: hidden; overflow- 
       y: scroll; "&gt;&lt;/iframe&gt;
     &lt;/body&gt;
  &lt;/html&gt;
</code></pre>

<p>But if we directly try url then all is fine.
url: <a href="http://mediamanager.b-" rel="nofollow noreferrer">http://mediamanager.b-</a> 
         yy.com/filemanager/newmediamanager/filemanager/dialog.php</p>
