WP images lazy loading is the new WordPress plugin that adds jQuery to WordPress and enables lazy loading in images. Thus improves your page loading times and makes your Google PageSpeed Score better than before.
Loading of images outside of the viewport (visible part of a web page)is delayed after the plugin is activated and hence the images won’t get loaded before visitor scrolls down to them.
Great for long pages containing a number of large images. This trick also reduces your server load and saves some of your bandwidth.
