Because I know what you all need is a timewaster:
http://games.usvsth3m.com/2048/15th-century-portraits-of-women-edition/ I think the portrait IDs are as follows, feel free to jump in or correct me!
2 = Portrait of a Woman with a Pearl Necklace, Lorenzo Costa, 1485-95
(can't ID 4 or 8 yet, hennin is Flemish?? padded headroll with chin veil ??French? German?)
16 (blond ringlets) = Portrait of a Woman, Domenico Ghirlandaio, 1490
32 (black U on forhead/veil on hennin) = PORTRAIT OF A YOUNG WOMAN ATTRIBUTED TO HANS MEMLING 1494 BRUGES
64 (blond horns with shoulder pin) = unknown artist Florentine School, 1475
128 (white veils, brown dress, green V trim, red band) = Rogier van der Weyden (Flemish painter, 1400-1464) Portrait of a Lady 1464
256 (red & gold brocade gown) = Rogier van der Weyden (Flemish painter, 1400-1464) Isabella of Portuagal 1445
That's as far as I can get.
