Hi patmatt69,
Sorry we can’t provide necessary code, You may use if condition to find the issue. This feature is also not available in you theme so you need to hire a developer too.
Ok If you want to display header image whose page id is 5 or any page id (Page id you need to find to display header)
This is simply logic
The code is inside clean retina pro -> library -> structure -> header-extension.php on line no 262 to 265, Replace these code <?php $header_image = get_header_image();
if( !empty( $header_image ) ) :?>
<a href="<?php echo esc_url( home_url( '/' ) ); ?>" title="<?php echo esc_attr( get_bloginfo( 'name', 'display' ) ); ?>"><img src="<?php echo $header_image; ?>" class="header-image" width="<?php echo get_custom_header()->width; ?>" height="<?php echo get_custom_header()->height; ?>" alt="<?php echo esc_attr( get_bloginfo( 'name', 'display' ) ); ?>"></a>
<?php endif; ?>
and add this
<?php $header_image = get_header_image();
$id = get_the_ID();
if($id == 5){
if( !empty( $header_image ) ) :?>
<a href="<?php echo esc_url( home_url( '/' ) ); ?>" title="<?php echo esc_attr( get_bloginfo( 'name', 'display' ) ); ?>"><img src="<?php echo $header_image; ?>" class="header-image" width="<?php echo get_custom_header()->width; ?>" height="<?php echo get_custom_header()->height; ?>" alt="<?php echo esc_attr( get_bloginfo( 'name', 'display' ) ); ?>"></a>
<?php endif;
}?>
Here you need to find the page id where you want header,We recommended not to change the code because if you change the code then while updating to our new version all your customisation code will be lost. So better make child theme and first unhook the functions and the edit the code.
