Hello @mtp525,
The current layout of the catch base theme places the featured image below the menu as per theme design. If you wish to display the header image above the menu you will need to modify the structure via child theme approach.
For further info on using child theme, please see the link here :

You can also automate the task using the child theme generator plugin.
After creating and activating the child theme, paste in the below code in your child theme’s functions.php file :
function catchbase_featured_image_display() {
add_action( 'catchbase_after_header', 'catchbase_featured_overall_image', 10 );
} // catchbase_featured_image_display
This will move the header image display above the primary menu.
Also, for future reference, you can also post your queries to the theme’s official support forum for swift and dedicated support at :

Hope this Helps,
Best Regards !!
