What this solution does
The module implements lazy loading for images, including background images, as well as for video and iframe elements. This optimizes Google PageSpeed scores by addressing the requirement to defer loading of hidden images.
LazyLoad PRO provides automatic lazy loading for images, videos, and iframe elements. The script independently identifies elements requiring optimization without the need for manual class or attribute configuration. It supports complex background images composed of multiple layers and handles both vertical and horizontal scrolling. Content appears smoothly. The module operates independently of jQuery and is compatible with composite modes, AJAX requests, and CDN services. Server-side performance (PHP) averages 0.01 seconds per page. The tool is fully SEO-friendly, ensuring images remain accessible to search engines even when the src attribute is absent in the source code.
Functionality includes processing images in the src attribute of img tags, as well as background images defined via CSS properties background and background-image. Support is provided for video tags and nested source tags, along with iframe handling. The srcset attribute is supported for adaptive rendering of images at different resolutions (configured manually). The system can generate placeholders based on the actual dimensions of source files. Exclusion mechanisms are available: lazy loading can be disabled for elements with specific classes or for images containing particular strings in their URL, which is useful for tracking pixels and retargeting tags.
The module allows disabling lazy loading for specific domains, sections, or individual pages.
To resolve the issue of resources blocking rendering, you can use the Resource Preloader module.
To reduce the size of HTML, JavaScript, and CSS code, use a dedicated minification module.

LazyLoad LITE - Deferred Image Loading
The module automatically adds the loading="lazy" attribute to images within img tags, enabling deferred loading without JavaScript. This is a lightweight version of the LazyLoad module that operates exclusively with img elements. Unlike standard solutions, it requires no script execution; the browser handles image loading natively using the attribute introduced in 2019.
