Lazy loading makes your site load faster and saves bandwidth.
This plugin replaces all your post images, post thumbnails, gravatar images and content iframes with a placeholder and loads the content as it gets close to enter the browser window when the visitor scrolls the page. Also works with text widgets.
Since it works with iframes, it also covers embedded videoes from YouTube, Vimeo etc.
You can also lazy load other images and iframes in your theme, by using a simple filter.
Non-javascript visitors gets the original element in noscript.
Compatible with the <a href="https://wordpress.org/plugins/ricg-responsive-images/" rel="ugc">RICG Responsive Images</a> plugin for responsive images.

echo $img_html;
?>
