Function to call default or uploaded cover image?

I use this function to call on uploaded cover image

      <?php // Get the Cover Image
        $member_cover_image_url = bp_attachments_get_attachment('url', array(
          'object_dir' => 'members',
          'item_id' => bp_loggedin_user_id(),
        ));
      ?>
<img src="<?php echo $member_cover_image_url; ?>">

With yours plugin this does not work, how to fix it?
