## Description

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](http://www.artzstudio.com/files/jquery-boston-2010/jquery.sonar/)
by Dave Artz (AOL).

## Installation

 1. Upload the plugin to your plugins directory
 2. Activate the plugin through the ‘Plugins’ menu in WordPress
 3. Enjoy!

## 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.

Having this plugin installed on my WordPress pages for some time resulted in having
them all malware-infected which happened literally yesterday. The plugin had its
name changed to some ‘WordPress CMS module’ and its directory name was changed as
well.

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

I hate plugins that don’t have any sort of settings or anything. I can’t tell if
it’s actually doing anything. How can I check?

 [Naoise Golden Santos](https://profiles.wordpress.org/ngolden/) فبراير 10, 2019

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.

sliders.
