Less is enough.

Enable or Disable LessFlux Lazy Loading

Lazy loading delays the loading of images until they are actually visible on the screen. LessFlux includes its own lazy loading system, which can be enabled or disabled depending on your setup.

This feature improves initial page load time, especially on pages with many images.

What lazy loading does

Instead of loading all images at once, lazy loading only loads images when they are about to enter the viewport.

  • images below the fold are not loaded immediately
  • initial page load becomes lighter
  • bandwidth usage is reduced

This results in faster perceived performance, particularly on mobile devices.

How LessFlux handles lazy loading

When enabled, LessFlux replaces WordPress’s native lazy loading behavior and applies its own implementation.

  • images are loaded dynamically as users scroll
  • loading behavior is handled by LessFlux
  • WordPress native lazy loading is disabled

This ensures consistent behavior across your site.

Where to find this setting

  • Go to LessFlux settings
  • Find the “Lazy load images” option
  • Enable or disable the feature

For most websites, lazy loading should be enabled.

  • improves page load performance
  • reduces unnecessary image loading
  • works well with most themes

This is especially useful for pages with many images, such as blogs, galleries, or ecommerce listings.

When to disable lazy loading

There are situations where you may want to turn this off:

  • you are already using another lazy load plugin
  • your theme includes its own lazy loading system
  • images above the fold need to load immediately for design reasons

Using multiple lazy loading systems at the same time can cause conflicts or unexpected behavior.

Inline aspect ratio setting

LessFlux also provides an option to add inline aspect ratios to images.

  • helps reserve space before images load
  • prevents layout shifts

This should remain enabled when using lazy loading.

Common issues

If images are not displaying correctly, check the following:

  • lazy loading is not conflicting with another plugin
  • images are not blocked by JavaScript errors
  • critical images are not being delayed unintentionally

If problems appear, try disabling lazy loading temporarily to confirm the cause.

Best practices

  • enable lazy loading for most websites
  • avoid running multiple lazy loading systems
  • keep inline aspect ratio enabled to prevent layout shifts
  • test important pages after enabling the feature

Lazy loading is a simple way to improve performance, but it should be used carefully to avoid conflicts with other optimization tools.
