Download Released

This module improves image loading performance by delaying the loading of images
outside the viewport and by temporarily showing lightweight versions of large
images while they are being fetched. This speeds up the initial page rendering.

It is particularly useful for websites with heavy visual content, such as
photography or art galleries. Faster rendering enhances user experience and may
also contribute to better search engine ranking.

Features

  • Defers image loading until they appear in the visible part of the browser
    window (lazy loading).
  • Displays a smaller version of an image until the full-size version has
    finished loading.
  • Allows restricting the module’s behavior to specific pages.
  • Allows restricting the module’s behavior to images above a minimum file size.
  • Optionally can show a blank image instead of a small preview image.

Known issues

  • Does not apply to background images (not using the img tag), such as those
    in a hero block.
  • May not work with images located outside the default public file directory as
    defined in Administration > Structure > File types > File settings.
