If your site is loaded with tons
of images, then chances are, it’s going to take years to load, leaving your
visitors frustrated for waiting too long to load. Most probably, they will wait
a few seconds and then move for any other site. 

Lazy loading effectively overcome
this failure by reducing loading time and significantly speed up images loading
velocity.

Lazy loading feature enables only
those images to load that comes into view in the visitor’s browser. Therefore,
if you own a site loaded with large images, then the lazy loading will load
only a few images that are “above the fold,” and the rest will automatically
load once the visitor scroll down to the page.

To help you find out the best lazy loading plugin for your site, I have hand-picked some great plugins that offer the same functioning with a variety of options.
