automattic / jetpack-lazy-images example snippets


/*
 * 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
