Lazy Load

Lazy load images to improve page load times. Uses jQuery.sonar to only load an image when it’s visible in the viewport.

Uses jQuery.sonar by Dave Artz (AOL).

FAQ

How do I change the placeholder image

add_filter( ‘lazyload_images_placeholder_image’, ‘my_custom_lazyload_placeholder_image’ );
function my_custom_lazyload_placeholder_image( $image ) {
return ‘http://url/to/image’;
}

How do I lazy load other images in my theme?

You can use the lazyload_images_add_placeholders helper function:

if ( function_exists( 'lazyload_images_add_placeholders' ) )
    $content = lazyload_images_add_placeholders( $content );

Or, you can add an attribute called “data-lazy-src” with the source of the image URL and set the actual image URL to a transparent 1×1 pixel.

You can also use output buffering, though this isn’t recommended:

if ( function_exists( 'lazyload_images_add_placeholders' ) )
    ob_start( 'lazyload_images_add_placeholders' );

This will lazy load all your images.

Reviews

Very Good

After 3 month of usage i can say that it is a good plugin and also i can give my rating as 5 stars.
It will make your website load faster.

Super fast and light

Worked right away, no setup work needed. The plugin is less than 10KB, makes my gallery blog way faster, loads reverse up when using TOC anchors (big plus), keeps DOM elements as IMGs, and has a good display. Exceeded all expectations! This is my new go to plugin.

Semplice e efficace

Ho usato questo plugin un sacco di volte e non ho mai avuto dei problemi.

Per questo gli do 5 stelle e lo raccomando a tutti i miei clienti che hanno bisogno di una soluzione per il lazy loading delle immagini.

Parlo dello stesso plugin anche in questo articolo che spiega come migliorare le prestazioni di WordPress
