Fisheye_Lazyload

Overview

A Magento 2 module that adds support for lazy loading of images.

Features

• Utilises the lazysizes script to add lazy load support for images
• Lazy loading is automatically applied to all* product images
  • *Any image created via Magento\Catalog\Block\Product\Image
  • This includes:
    • Product listing (category, search, product list widget)
    • Product relations (related, upsell, crosssell)
    • Product comparison
    • Recently viewed
    • Cart thumbnails
    • Wishlist
• Support can be added to any further images by adding the following to <img> elements:
  • Add lazyload class
  • Change the src attribute to data-src
  • Optional: add a dummy src with transparent 1px x 1px image to avoid broken image links prior to lazy load (see product image templates as example)
  • Optional: add loading="lazy" to enable native browser lazy-loading where possible. Note that this is not true native lazy-loading, as the lazysizes script and its native-loading plug-in need to be run, so there's still a dependency on JavaScript before affected images will show.
• Preloading
  • Preloading means the media source will be loaded even if not in the viewport such as megamenu icons/images.
  • The preload_elements layout argument allows you to specify selectors of which elements can be preloaded. This can be configured per page.
  • Use the lazypreload class on element(s) you wish to preload.

Compatibility

• Magento Community Edition / Enterprise Edition 2.4.x (see older releases for 2.0 - 2.3 support)
• Supports Magento 2 Full Page Cache (including Varnish)
