How can I optimize my website's loading speed using lazy loading for images?

Asked on Dec 17, 2025

Answer

Lazy loading is an effective technique to improve your website's loading speed by deferring the loading of images until they are needed. This approach is particularly useful for pages with numerous images, as it reduces initial load time and bandwidth usage.

<!-- BEGIN COPY / PASTE -->
    <img src="placeholder.jpg" data-src="actual-image.jpg" class="lazyload" alt="Description">

    <script src="https://cdnjs.cloudflare.com/ajax/libs/lazysizes/5.3.2/lazysizes.min.js" async></script>
    <!-- END COPY / PASTE -->

Additional Comment:

Use the "lazyload" class to target images for lazy loading.
Ensure the "data-src" attribute contains the path to the actual image.
Include the lazysizes library to handle the lazy loading process.
Consider using native lazy loading with the "loading='lazy'" attribute for modern browsers.
Test the implementation across different devices and browsers to ensure compatibility.
