title: Fotorama slider - how to Lazy Load images and then unload them when not visible?
body: <p>I'm using <a href="https://fotorama.io/" rel="nofollow noreferrer">fotorama.io</a> on my site and I have a large gallery of images in the slider (60-80) so I followed the suggestion in the manual to use Lazy Load to not load all my images at once.</p>
  <p>But when I browse images and already reached 40+ images, my browser memory is overloaded and the browser is starting to respond slowly, I have Memory Restart plugin for Firefox which shows my memory to build up very high.</p>
  <p>Is there a way to use lazy load and keep for example 10 images, and unload all the not visible or images that are as far as 10+ to unload so that memory is cleared?</p>
