Display logged in users cover image in sidebar

I am trying to add the currently logged in users profile info along with a cover image to the activity page on my buddypress site. At the moment I am using this code to echo out the profile data at the top of my my activity.php however for some reason the cover image is not displaying.

<div class="activity-sidebar-left">

<div id="item-header" role="complementary">

    <?php

    add_filter('bp_displayed_user_id','bp_displayed_outside_bp');
  function bp_displayed_outside_bp($id){
return ($id==0) ? get_current_user_id() : $id;

 }
   if ( bp_displayed_user_use_cover_image_header() ) :
        bp_get_template_part( 'members/single/cover-image-header' );
    else :
        bp_get_template_part( 'members/single/member-header' );
    endif;
    ?>

</div><!-- #item-header -->
</div>

How would I go about adding the users header cover image?
