LLFJ loads images only when the are needed - Plugin for Joomla!

Plugin: LLFJ - Lazy Load for Joomla!
Function: Images are loaded only in the visible area - Advantage: save bandwidth and load the pages much faster
Languages: English / German
Joomla! Version: >=3.2 (free version)
Script: Lazy Load by David Walsh (Mootools) / Lazy Load Plugin by Mika Tuupola (jQuery)

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.

LLFJ uses the script "Lazy Load" by David Walsh. No extended Framework (such as jQuery) is required, because the script uses Mootools! All information to the script: Lazy Load

The script only works if JavaScript is activated in the browser.

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.

On 28 January 2012 the version 2.5-1 for Joomla! 2.5 was released.

In version 2.5-2 you can exclude certain images from being processed by the plugin.

In version 2.5-3 three user suggestions were implemented: eclusion of bots, toggle the selection and disable the script if the Joomla! editor is loaded.


  • Images are loaded only in visible areas (viewport)
  • Supported frameworks: jQuery / Mootools
  • Loading effects: Fade in / Show
  • 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
  • Toggle selection - entered data are not excluded, but included


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.

  • + 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.)

Version 3-5 - 2014-07-10
