I read this thread that is closed:
It seems the files have changed since then, so it is not easy to find what I need to get this done. Of course i found custom-header.php and saw how that can be edited.
define( ‘HEADER_IMAGE’, $headerpath ); // %s is theme dir uri
define( ‘HEADER_IMAGE_WIDTH’, 970 );
define( ‘HEADER_IMAGE_HEIGHT’, 80 );
The issue I have is there header space is still not allowing this now larger image when I change to 200. Any help with that would be appreciated.
