agreed i have most of my experience in book design mostly history of book design pre gutenbergian period and do consider myself only vaguely familiar with web design but i understand that through history images have posed a problem to book designer if images exist there on the page in their own right and the page is as much an image as a carrier of the text the layout can be and usually is creative but in such towards written information and legibility orientated enterprises as wikipedia this is not a sensible approach furthermore the images are only thumbs pointers and only full size image gives the full impression so i see no particular reason for playing around with incomplete images what serve only as reference marks
