How do I implement lazy loading for images in WordPress?

Lazy loading is now built into WordPress core (version 5.5+), automatically deferring off-screen images. To enhance this feature:

  • Ensure your theme supports native lazy loading
  • Add loading=’lazy’ attribute to image HTML if needed
  • Use a3 Lazy Load plugin for additional options
  • Consider lazy loading for iframes and videos too

To verify lazy loading is working, check your page source for loading=’lazy’ attributes on img tags. For more advanced features like custom threshold distances or effects, consider using specialized lazy loading plugins.
