Enluminures is a French archive of images from illuminated manuscripts. It has digital galleries covering war, eating in the Middle Ages, and the hunt, as well as several other subjects. (Note the tiny page indicators at the top of the galleries.) Most of the images are available through the search page, however, which includes not only subject, title, creator and type of decoration indexes, but also the ability to look only at one library's contributions. Other threads about illuminated manuscripts here.
[Unfortunately, this French site uses Javascript to link to images and I couldn't figure out a way to present examples here.]
