Is there a code to disable lazy loading of wordpress site logo?

You can disable Lazy Load on Specific Images by using the Hook Below

Place the Hook in your functions.php file

    /* Disable lazy loading by image ID and size */
    function wphelp_no_lazy_load_id( $value, $image, $context ) {
    if ( 'the_content' === $context ) {
    $image_url = wp_get_attachment_image_url( 4532, 'large' ); // Change the ID and size
    if ( false !== strpos( $image, ' src="' . $image_url . '"' )) {
    return false;
    }

}
return $value;
}
add_filter( 'wp_img_tag_add_loading_attr', 'wphelp_no_lazy_load_id', 10, 3 );
