Lazy Load XT

Lazy load images, YouTube and Vimeo videos, and iframes using Lazy Load XT.

Lazy Load XT is the fastest, lightest, fully customizable lazy load plugin in the WordPress Plugin Directory.

This plugin works by loading the Lazy Load XT script and replacing the src attributes with data-src when the content of a post or page is loaded on the front end of a WordPress site.

1. Install and activate the plugin through the ‘Plugins’ menu in WordPress

or

1. Download and unzip Lazy Load XT.
2. Upload the lazy-load-xt folder to the /wp-content/plugins/ directory
3. Activate the plugin through the ‘Plugins’ menu in WordPress

Why aren’t my images lazy loading?

Lazy Load XT filters images added to the page using the_content, post_thumbnail_html, widget_text and get_avatar. If your images are added using another function (wp_get_attachment_image for example), Lazy Load XT does not filter them. However, as of v0.4, you can filter the HTML yourself by passing it to get_lazyloadxt_html.

For example, if a theme has:
echo wp_get_attachment_image($id);
Changing it to the following would lazy load the image:
echo get_lazyloadxt_html( wp_get_attachment_image($id) );
