Maximizing Speed with Lazy Loading Images: Your Secret to Success

At Bits Kingdom, we understand the importance of speed when it comes to websites. And we’re thrilled to share a valuable industry secret with you: the use of lazy loading images to enhance site speed. Intrigued? Let’s jump right in!

Why Choose Lazy Loading?

Implementing lazy loading images is an efficient technique to amp up your website speed. The method ensures that images load only when they appear in the browser viewport. This can be done by adding the ‘loading=”lazy”‘ attribute to the image tag. Easy-peasy!

<img source="image.jpg" alt="bits tips image" loading="lazy"></img>

But what if your site is bursting at the seams with images? It could become tiresome to manually assign the attribute to each one of them. No worries, though! There’s a simple solution: JavaScript to the rescue!

The Power of JavaScript

With this nifty JavaScript script, every image gets the lazy loading attribute, loading only when they come into the viewport view. This one trick can remarkably rev up your website’s speed.

document.addEventListener("DOMContentLoaded", function () {
	var lazyImages = [].slice.call(document.querySelectorAll("img.lazy"));

	if ("IntersectionObserver" in window) {
		let lazyImageObserver = new IntersectionObserver(function (
			entries,
			observer
		) {
			entries.forEach(function (entry) {
				if (entry.isIntersecting) {
					let lazyImage = entry.target;
					lazyImage.src = lazyImage.dataset.src;
					lazyImage.classList.remove("lazy");
					lazyImageObserver.unobserve(lazyImage);
				}
			});
		});

		lazyImages.forEach(function (lazyImage) {
			lazyImageObserver.observe(lazyImage);
		});
	}
});

And that’s the final piece! Witness the acceleration in your website loading speed!
