Add div around lazyload_placeholder_image ?

Hi there I was wondering how you would add a div around the custom lazy loaded image?

add_filter( 'lazyload_images_placeholder_image', 'my_custom_lazyload_placeholder_image' );
function my_custom_lazyload_placeholder_image( $image ) {
	return 'IMAGE-URL';
}
