Disable LazyLoad on Specific Images

You can use the field in the plugin settings to exclude images and iframes from LazyLoad:

To exclude an image, use any keyword from the image tag such as: filename, CSS class, any attribute, or domain name (for externally hosted images). 

Note: All exclusion methods can be used for background images as well as standard images.

Example

If you would like to exclude the following image: 

<img src="http://www.example.org/wp-content/uploads/daniele-riggi-635135-unsplash.jpg" class="attachment-full size-full" data-imgsrc="http://www.example.org/wp-content/uploads/daniele-riggi-635135-unsplash.jpg" alt="unsplash image" title="image title"/>

You could use any of the following:

• Filename: daniele-riggi-635135-unsplash.jpg
• Class: attachment-full size-full - this will exclude all images with both these classes
• Class: attachment-full or size-full -  this will exclude images with either specific class
• -unsplash - this will also exclude any other image with -unsplash in the filename
• Contents of the alt text: unsplash image
• Contents of title attribute: image title
• Custom attribute name: data-imgsrc

Note: The keywords(Filenames, CSS classes, CSS Ids, alt texts, title attributes, attribute names) can be found in the source code of the page.

Tip for Elementor images widget

Images integrated with the Elementor image widget can be problematic to exclude sometimes. Using a CSS class does not work because Elementor is not adding it to the image tag but to a parent div tag, so you’ll have to put every single filename in the exclude settings. 

A workaround is possible with this plugin: https://wordpress.org/plugins/add-class-to-elementor-image/. 

Just add this class no-lazy in WP Rocket's LazyLoad exclusion field and add no-lazy in the Custom Class field of every image you don’t want to be LazyLoaded by WP Rocket.
