title: Get all images in a div using vanilla JS
body: <p>I'm doing some complex interprocess JS on unknown pages so jquery is out of the question. How do I get all images within a div provided I have the ref of the div? </p>
  
  <p>Something like :</p>
  
  <pre><code>document.getElementsByTagName("img")
  </code></pre>
  
  <p>But only within a div.</p>
