Optimizing responsive images is crucial for improving page load times and enhancing user experience. By using techniques like the `srcset` attribute and appropriate image formats, you can ensure images are served efficiently based on the user's device and screen size.

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

Additional Comment:

Use the `srcset` attribute to define multiple image sources for different screen resolutions.
Include the `sizes` attribute to specify the image display size for various viewport conditions.
Consider modern image formats like WebP for better compression and faster load times.
Implement lazy loading with the `loading="lazy"` attribute to defer offscreen images.
