With this plugin images are only loaded when a visitor scrolls to the images. It saves your server bandwidth and saves your users from load images that they never scroll to. This increases the loading speed of all pages.

If there are problems in the output of some components, they can be excluded in the settings. LLFJ is not running in excluded components and the pages will load normally.


  • Images are loaded only in visible areas (viewport)
  • Supported frameworks: Built-in lazy-loading attribute (Pro only) / Plain JavaScript (Pro only) / jQuery
  • Threshold feature - preloads images within specified range (in pixels)
  • Saves bandwidth
  • Increases the loading speed of all pages
  • Nice fade-in effect
  • No additional external framework required
  • Exclude images
  • Exclude components
  • Exclude URLs
  • Exclude Bots - search engines can index the images
  • Exclude in Joomla! Editor - the plugin is not triggered if the editor is loaded

Install the plugin by accessing the administration menu of the back-end under Extensions. Then access Extensions - Plugins - System - Lazy Load and activate it!

The plugin only has to be activated, there are no further adjustments necessary. Easy and effective!

If there are problems loading the images, certain images, components or URLs can be excluded in the settings.

If you don't see any images after the plugin activation, please open the browser console and check whether a JavaScript error is thrown. This does not apply to the native built-in attribute from the PRO version!

It's written in plain "vanilla" JavaScript, it leverages the IntersectionObserver API, it supports responsive images and enables native lazy loading. Thanks to Michael K. for the suggestion of the implementation!

    • + Threshold in pixels (jQuery script only) - By default images are loaded when they appear on the screen. If you want images to load earlier use threshold parameter. Setting threshold to 200 causes image to load 200 pixels before it appears on viewport. (Description from the project website of the jQuery script.)
