SW Lazy Load is a no brain plugin that allow's you to load only images when they are needed.
This plugin is the a no brain solution to implement lazy loading on your website. After activated the plugin will only load the images when they are needed to be shown to user.
This plugin replaces all your images by a placeholder and it loads the content when gets closer to the browser viewport, when visitor scrolls down.
Unlike most of the lazy loading plugins, SW Lazy Load makes a complete page parse for images to apply the rules. This ensures that the images you use on your themes will also be covered with the lazy loading.
The plugin uses the 'unveil.js' as support for the functionality. Credits for this lib on ( https://github.com/luis-almeida/unveil )
