Hi amfiska,
We have designed our theme this way. The header image arise at the top of the page. You need code customisation for it. The file is inside theme folder -> inc -> structure -> header-extension.php

You may customise the code but 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.

Thank you!
