How can I implement lazy loading for images in WordPress?

Lazy loading delays loading images until they’re about to enter the viewport, improving initial page load times. Here’s how to implement it:

  • WordPress 6.0+ includes native lazy loading support – no plugin needed for basic functionality
  • Add loading=’lazy’ attribute to image tags automatically
  • Use the a3 Lazy Load plugin for advanced features

For optimal implementation:

  • Prioritize above-the-fold images by excluding them from lazy loading
  • Use proper image dimensions to prevent layout shifts
  • Consider using low-resolution placeholders

The a3 Lazy Load plugin offers additional features like custom threshold distances and support for iframes and videos.
