title: Javascript if (document.images)
body: <p>I'm analysing other person JavaScript code and found this condition</p>
  
  <pre><code>if (document.images)
  </code></pre>
  
  <p>I foun on other sites that it is used to verify if browser supports dynamic images. Something like when we put mouse over image, other image is loaded. It's looks like very old JavaScript. Is it makes sense to use it nowadays? Is this condition have another objective?</p>
