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.

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.

Seems to work for some images but not for all, with no real explanation about why. There are no configuration options so I couldn't find a way to fine-tune it.

The idea might be good but its messing up the entire websites, mostly on different sliders.

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.
