Lazy loading images can significantly improve page load time by deferring the loading of non-essential images until they are needed. This reduces initial page load size and speeds up rendering by prioritizing visible content.

Example Concept: Lazy loading delays the loading of images that are not immediately visible in the viewport. By using the "loading='lazy'" attribute in the tag, browsers can prioritize loading only the images that are needed for the initial view, reducing the number of HTTP requests and the amount of data transferred during the initial page load.

Additional Comment:

Lazy loading is particularly beneficial for pages with many images, such as galleries or long articles.
It helps improve the Largest Contentful Paint (LCP) by reducing the time it takes to load the main content.
Ensure that lazy loading is implemented correctly to avoid images not loading when they come into view.
Test lazy loading across different devices and browsers to ensure compatibility and performance gains.
