title: Image not showing in push notification
body: <p>I am using the notification payload below and use Postman to send a push notifications to Android devices:</p>
  
  <pre><code>{
      "to" : "/topics/xxxx" ,
      "data" : {
          "url" : "https://res.cloudinary.com/demo/image/upload/w_200/lady.jpg",
          "dl" : ""
      },
      "notification" : {
          "title" : "This is a sample notification from general2",
          "body" : "Rich notification testing (body)",
          "image": "https://res.cloudinary.com/demo/image/upload/w_200/lady.jpg"
      }
  
  }
  </code></pre>
  
  <p>I have used the <code>image</code> key value pair to include an image in the push notification. My expected output is:</p>
  
  <p><a href="https://i.stack.imgur.com/lyJP6.png" rel="noreferrer"><img src="https://i.stack.imgur.com/lyJP6.png" alt="enter image description here"></a></p>
  
  <p>But this is what it is showing in the phone:</p>
  
  <p><a href="https://i.stack.imgur.com/yQl07.png" rel="noreferrer"><img src="https://i.stack.imgur.com/yQl07.png" alt="enter image description here"></a></p>
  
  <p>As you can see, the image is not appearing. What might be the problem?</p>
