Reply To: Moving Featured Image Under Post Ttitle

To move the Featured Image under the Page Title, add this to your functions file –

remove_action( 'genesis_entry_content', 'genesis_do_post_image', 8 );

add_action( 'genesis_before_entry_content', 'genesis_do_post_image', 1 );

If you want to move it to a different location, take a look here at the Hook list – https://my.studiopress.com/documentation/hooks/hooks/hook-reference/

Let me know if that helps
