Yes you should, but you need to keep in mind that's something you need to update every time you change something in your interface. It is incredibly frustrating when screenshots don't match what you see on screen, especially if you're a new user (i.e. the key audience for documentation). There's a horrible sense of doubt whether you're doing things correctly. Probably another reason why you shouldn't change your GUI that often.
