Hi please go throught theme folder (interface) -> inc -> structure -> header – extension.php on line no 361.
From there your header image is displayed. If you are good at coding then you can make a condition from there too.
We recommended not to change the code because if you change the code then while updating to our new version all your customization code will be lost. So better make child theme and first unhook the functions and the edit the code.
