title: Using Discord.js to check the url of an image in an embed
body: <h2>The idea</h2>
  
  <p>What I seek to do, is upon a message being sent, if that message is an embed, I want my bot to check the image in that embed (if there is one) for it's url, and if the url matches a specific url I provide, for the bot to send a specific message that I provide. </p>
  
  <h2>The issue</h2>
  
  <p>While I know the event for messages being sent (<code>client.on("message", function(message) {</code>)
  I have <em>no</em> idea how to have the bot check to see if that message is an embed, and how to have it check the url of the image in that embed, if there is one.</p>
