How can I optimize image loading for better performance on mobile devices?

Answer

Optimizing image loading is crucial for improving performance on mobile devices, as it reduces load times and enhances user experience. Techniques such as lazy loading, responsive images, and proper image formats can significantly contribute to better performance.

<!-- BEGIN COPY / PASTE -->
    <img src="image.jpg" 
         srcset="image-small.jpg 480w, image-medium.jpg 800w, image-large.jpg 1200w" 
         sizes="(max-width: 600px) 480px, (max-width: 1200px) 800px, 1200px" 
         loading="lazy" 
         alt="Description of image">
    <!-- END COPY / PASTE -->

Additional Comment:

Use "srcset" and "sizes" attributes to serve appropriately sized images based on the device's viewport.
Implement "loading='lazy'" to defer offscreen images until the user scrolls near them, reducing initial load time.
Choose modern image formats like WebP for better compression without losing quality.
Consider using a Content Delivery Network (CDN) to deliver images faster to users worldwide.
