Up here in where I am most restaurants have pictures on every page of the menu. For example Earls, Joeys, Red Robins, Boston Pizza. Menu's that don't have pictures often feel cheap and non-professional.
Where do you live? In Vancouver, Earls and Joeys don't have pictures on their menus. Red Robins and BP do, but they're definitely a tier below the former two.
