This plugin adds the <code>loading</code> attribute to IMG tags found when filtering <code>the_content()</code> to support native image lazy loading.
For more information about lazy loading images using this new native browser image attribute, check out this article: <a href="https://addyosmani.com/blog/lazy-loading/" rel="nofollow ugc">https://addyosmani.com/blog/lazy-loading/</a> and for a little more depth into what we’re doing here, check out our <a href="https://jdmdig.it/30nXp7h" rel="nofollow ugc">explainer post</a>.
Historically, to limit the impact offscreen images have on page load times, developers have needed to use a JavaScript library (like <a href="https://github.com/aFarkas/lazysizes" rel="nofollow ugc">LazySizes</a> or <a href="https://www.andreaverlicchi.eu/lazyload/" rel="nofollow ugc">Vanilla-LazyLoad</a>) in order to defer fetching these images until a user scrolls near them. What if the browser could avoid loading these offscreen images for you?
The <code>loading</code> attribute instructs a browser to defer loading offscreen images until users scroll near them. It comes in three flavors: eager, auto, and lazy. Install this plugin and you can set the first image’s loading attribute and the loading attribute for all the subsequent images sent through <code>the_content()</code> in the plugin’s settings page.
Simple is Beautiful
There is no JavaScript or CSS included in the plugin. It just works in browsers that support the new <code>loading</code> image attribute.
For browsers that don’t support this new image loading attribute, that’s ok. You can still use whatever JavaScript-based image lazy loader you want as a fallback until browser support becomes a little more mainstream.

Native Image Lazy Loading

Automatically add the new loading attribute to images within your content to support native image lazy loading.

This plugin enhances page load times by loading only the YouTube video preview image initially. Additionally, it offers the option to make your video sticky, positioning it at the top or bottom of the window when the user scrolls away from the video viewport.
<h3>Features</h3>
<ul>
<li>Lazy Load Videos: Reduce the amount of time it takes to load your video by loading just the video thumbnail.</li>
<li>Multiple Video Support: You may quickly and simply add more than one video to a page. Videos can only be played one at a time, and when one is playing, the other one instantly pauses.</li>
<li>Sticky Video: Keep videos visible as you navigate by adhering them to the top or bottom of the screen to ensure ongoing playback.</li>
<li>Custom Styling: Adapt your videos’ look to perfectly match the style of your website by using your own CSS.</li>
</ul>
