What Is Lazy Load and How Does It Work?
WordPress lazy load refers to a technique that delays the loading of media files until users scroll down to the specific position of that image or video. This means that, instead of loading all images on a page at once, it shows files above the fold only. The images that haven’t been loaded yet will be replaced with a placeholder or blank space.
Since the release of WordPress 5.5, the platform has built lazy loading as a default feature. To explain how this function works, WordPress adds the tag loading=”lazy” to all img tags (image tags) that include width and height attributes.
Still, you can customize the native image lazy loading or the lazy load background with the help of plugins.
Why Your Should Lazy Loads Images in WordPress
You have multiple reasons for delaying WordPress image loads. First and foremost, it helps boost website speed which leads to better website performance. This method greatly improves the user experience on your site too.
Optimize WordPress Site Loading Time
Slow websites frustrate users, even the most patient visitors. It’s estimated that about 40% of users will leave your site if it makes them wait for more than 3 seconds. And images significantly contribute to your page speed.
Fortunately, lazy-loading images cut off the weight of your webpage resulting in quicker page load. Rather than taking time loading the entire page with all images, it just shows images when users scroll down to a certain page area. So visitors can access your site content faster.
Reduce Website Bandwidth
Anytime users load your page, it sends a bandwidth request to your server. As normal, when users open a page, it will deliver the entire page content to them even though they just scroll down to the middle of your page. This wastes a lot of your resources.
WordPress lazy load helps optimize resources and save your hosting cost by just requesting bandwidth of the loaded content.
Improve User Experience

To protect your WordPress files with the PDA Gold plugin, you first install it then go to the Media Library in your admin dashboard. Now find your desired image to secure and click ‘Protect’ under its name.
Hit ‘Configure file protection’ option of the protected file and you’ll see a Private File Management Popup. Here you can either auto-generate new random quick access links or customize your own manually.
The popup shows all elements of your protected file. They are private download links, status, the total number of clicks, download limit, download expiry, created time. Besides, there are options to edit, copy, expire, and delete each link.
It’s possible for you to protect multiple files at a time using a bulk action. Simply go back to the Media Library and check on files that you intend to protect. After that click on the Bulk actions dropdown, select ‘Protect files’, and press Apply.
