Setting different Header Image to different pages

Hi! I´m trying to set a different header image for each page in my website but when I set an image it appears on the whole site ("booking" & "villa" pages, excluding homepage because I´m using a header video) and I´m kinda stuck here, also I would love to hide the header image in my gallery page so it would just be pictures without header image. How could I solve this problems? Thank you very much! URL: www.villacoralillo.com
