Overview
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 RICG Responsive Images plugin for responsive images.

My suggestion would be to set the threshold from 200 to 300 now my site is not only far faster but also loads correctly.
I also use plugins like…
Far Future Expiration Plugin
Fast Velocity Minify
Webcraftic Clearfy – WordPress optimization plugin
To get my speeds this high.
The only thing I would suggest is an update from the developer so its inline with the latest WordPress. However, on my latest WordPress, my website still seems faultless with this outdated plugin.

A Good Plugin
by Eric Farmer·6 years ago
I downloaded this plugin because I wanted my images to load better for my blog readers. It works great, and once setup, I can just let it do its thing.
