01. What is Lazy Loading

A Lazy Loading is an advanced feature that tells browsers to defer the loading of images until page visitor scrolls near them. It improves the performance (loading speed) of a page and saves the resources such as bandwidth.

You can see in this video that images are being loaded only as I scroll/reach near them.

When Lazy loading is enabled you can see the image attribute Loading=”lazy” on the Image tag <img> also known as Image Embed Element, in the Page Source, as shown below.

When Lazy loading is enabled you can see the image attribute Loading="lazy" on the Image tag <img data-lazyloaded=

02. Why it is Important to Disable Lazy Loading on Featured (LCP) Image

When Lazy Loading improves the loading speed of a page then why it is important to disable the Lazy Loading on Featured/LCP image or above-the-fold content?

The answer is, it can have a very bad effect on your page’s LCP (Largest Contentful Paint) timing because when an image in the viewport is lazily loaded the browser may defer it, that can increase its loading time. To provide a good page-experience to users, the content on the viewport should be immediately loaded.

LCP is one of the key metrics of Core Web Vitals that measures how long it takes for the largest element (image, text, heading, etc) to become visible in the viewport. The viewport is the visitor’s visible area of a web page on a device, as shown below.

The viewport is the visitor's visible area of a web page on a device, as shown below.

You can also test your pages on Google PageSpeed Insights to know whether your LCP images are being lazily loaded or not. If they are lazily loaded, it shows, “Above-the-fold images that are lazily loaded render later in the page lifecycle, which can delay the largest contentful paint.“.

Above-the-fold images that are lazily loaded render later in the page lifecycle, which can delay the largest contentful paint."

03. How to Install Custom Image Attribute Plugin

01. Using Custom Image Attributes Plugin

You must have installed the Custom Image Attributes plugin, now, in this section, I will guide you on how to remove the Loading=”lazy” on featured/hero image.

Here I am showing you how to remove Loading =”lazy” on a new featured image. You can follow this guide to do it for old/existing featured images. You can open your old featured images directly from the Media Library as well as from posts.

  • Inspect the source code of the featured image. You can see that the Loading=”lazy” is removed from the <img> tag of featured image.
  • You can also see the fetchpriority=”high” attribute that I have added through Custom Image Attribute plugin, as shown in the next section. This attribute tells the browser that this image has high priority and should be loaded quickly with other resources. It improves the LCP score/timing of featured image.
  • You can also test your page on Google PageSpeed Insights to know whether featured image is lazily loading or not, and how much LCP score is improved.
Inspect the source code of the featured image. You can see that the Loading="lazy" is remove from the <img data-lazyloaded=

02. Using LiteSpeed Cache Plugin

  • Scroll down to Lazy Load Image Class Name Excludes section and add the class of your Featured Image. I have added the class wp-post-image, which is the class of my site’s Featured Image. LiteSpeed cache will remove the data-lazyloaded=”1″ from my Featured image and it will not be lazily loaded. Learn more about HTML Classes.
  • Update the changes and Clear the Cache of LiteSpeed. Open a post and check whether Loading=”lazy” is removed or not.

In the next step, I have shown how to find the class of your Featured image.

Open the Media Excludes tab. Scroll down to Lazy Load Image Class Name Excludes section and add the class of your Featured Image.
  • Right-click on your Featured Image and click on the Inspect. It will open the HTML code of Featured image on the Developers tool.

In the Custom Image Attributes field enter fetchpriority="high". Click on the Save Changes button.

06. What is the Drawback of Removing Lazy Loading?

Though I have guided you to remove the Lazy Loading on Featured Image using the plugins, but there is a drawback of it.

When you remove Lazy Loading on Featured Image using the above solutions, Lazy Loading is also removed from all the thumbnails of your posts. As a result, when a page is loaded they all are quickly loaded with the Featured Image and other Critical Resources of your site, that increases the loading speed of a page particularly on mobile devices.

It is not recommended to load offscreen images with your Featured Image and Critical Resources. All the offscreen images are meant to be deferred using Lazy Loading.

Here the region highlighted with the red border is viewport (Viewport is the user’s visible area of a web page). The region highlighted with the green border contains offscreen thumbnails.
