Lazy Load

外掛說明

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

This plugin is an amalgamation of code written by the WordPress.com VIP team at Automattic, the TechCrunch 2011 Redesign team, and Jake Goldman (10up LLC).

Uses jQuery.sonar by Dave Artz (AOL).

安裝方式

  2. Activate the plugin through the ‘Plugins’ menu in WordPress
  3. Enjoy!

常見問題集

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.

It produces random grayed out pictures within Jupiter theme image galleries. The galleries work like charm after disabling this bundled plugin.

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.
