I would need help to change/optimize my start page (HOME), so that my own picture on the background image is always fully visible (shoulders inclusive) in all screen sizes (full HD and lower, including mobile view). Perhaps by defining my picture as an object? At the end it should be similar to the picture of the guy on this website (he gets smaller, when screen is smaller, but he is still fully visible): [url removed, login to view]
My page: [url removed, login to view]
The Wordpress theme I am using is called: "Simple" from Nimbus ([url removed, login to view])
The freelancer must be able to modify native wordpress code and must also be a pro in graphics and website design (incl. all required software tools, such as Photoshop).
