You can put it anywhere you want. All you need to do is creating a non-steam game title and right-click every blank picture area and go to "Manage" then "Set Custom Artwork" and select the proper picture.
For the header ones, you need to open the game and close it so it's header will be on home page. Right click the header, go to "Manage" then choose "Set Custom Artwork" and choose the header, it is done! Thank you for your feedback.
