This package is abandoned and no longer maintained. No replacement package was suggested.

Speed up your site and create a smoother viewing experience by loading images as visitors scroll down the screen, instead of all at once.

README

Speed up your site and create a smoother viewing experience by loading images as visitors scroll down the screen, instead of all at once.

Caution

This package is abandoned. WordPress Core now uses browsers' native lazy loading, and the code in here conflicts with the Interactivity API added in Gutenberg 16.6.

Usage

/*
 * Initialize lazy images on the wp action so that conditional
 * tags are safe to use.
 *
 * As an example, this is important if a theme wants to disable lazy images except
 * on single posts, pages, or attachments by short-circuiting lazy images when
 * is_singular() returns false.
 *
 * See: https://github.com/Automattic/jetpack/issues/8888
