Progressive Image Loading

Progressive image loading is a technique that revolutionizes the way images are displayed on web pages. Instead of loading the entire image at once, browsers gradually refine a low-resolution version, progressively enhancing the image’s quality as more data becomes available.

Why It Matters:

Traditional image loading can cause a “loading lag” that frustrates users. Progressive loading provides a more responsive and engaging experience, as users can see a preliminary version of the image while the high-resolution version loads in the background.

Implementation:

<img src="thumbnail.jpg" alt="High-Resolution Image" loading="lazy"> 

The loading="lazy" attribute tells the browser to load the image lazily, contributing to the page’s perceived loading speed.
