title: Sending an image without the link showing with discord library
body: <p>I would like my discord bot to send an image (from a url), but have the url be hidden from the message that is sent in chat. For sending messages, im using a switch statement that only uses the writing after an "!"</p>
  
  <pre><code>            case 'happy':
              bot.sendMessage({
                  to: channelID,
                  message: 'https://pictureexample.jpg'
              });
  </code></pre>
  
  <p>How would I send messages without having the link show in chat?</p>
