<p>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.</p>
<p>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.</p>
<h4>Will work on your theme images</h4>
<p>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.</p>
<p>The plugin uses the ‘unveil.js’ as support for the functionality. Credits for this lib on ( https://github.com/luis-almeida/unveil )</p>
<p>Please let me know if you need further help with the plugin.</p>
