Hi again @sayandutta,
I am afraid, you don’t have a specific class or id to be used for the mentioned image. So, adding its current class will also interfere with other images on the site as well.
Mu-plugins are generally used to change and trigger some options of the already installed plugins. You can use them to exclude this image by specifying it full path such as;
<?php
add_filter('smush_skip_image_from_lazy_load', function( $skip, $src, $image ){
//compare the $src here and return true to skip
if ( ! $skip && 'https://findnewscholarships.com/wp-content/uploads/2022/07/Case-Study-1-768x512.jpeg' === $src ) {
$skip = true;
}
return $skip;
}, 99, 3);
Another way to do is to create an id or custom class for this image on your page designer and use that on Smush Lazy Load exclusion section.
Kind regards,
Zafer
