The size you specify here is only for the back-end work of the admin • Number of values: from 1 to unlimited, depending on the case • Default image: rarely used, only if a feature or section requires an image, you can set one default to be displayed when the admin does not upload one Drupalist: Kalin Chernev Course by Init Lab (http://initlab.org) 15
