         <p>We've also set the scrollDelay (i.e. the delay between scrolling and replacing a placeholder with an image) to be very high (two seconds). This is so you can visually see the lazy-loading of images as they happen.</p>
         <p>The default value is 250ms but you can override that to your own preference.</p>
