Profile pages without cover image

I have cover images optional.
User profile pages without a cover image can reduce their page size by adding this php code to your (child) theme into /wpum/profiles/cover.php

// Exit if accessed directly
if ( ! defined( 'ABSPATH' ) ) exit;

$cover_image = get_user_meta( $data->user->ID, 'user_cover', true );

if($cover_image == '') {
?>
<div id="header-cover-image-none" style="width: 100%; z-index: 1; height: 175px; position: relative;">
<?php
} else { 
?>
<div id="header-cover-image" style="background-image: url(<?php echo $cover_image; ?>);">
<?php }
?>
	<div id="header-avatar-container">
		<a href="<?php echo esc_url( wpum_get_profile_url( $data->user ) ); ?>">
			<?php echo get_avatar( $data->user->ID, 128 ); ?>
		</a>
	</div>
</div>
