See "L'Ultima Cena" (The Last Supper) in detail.

As I mentioned in an earlier post, pictures are not allowed at Cenacolo Vinciano in Milan. However, I found a zoomable image of The Last Supper.

At this site you can also see the church of Santa Maria delle Grazie which houses the Leonardo masterpiece, as well as the fresco on the opposite wall, a crucifixion scene by Giovanni Donato Montofarno.

And this is beautiful Santa Maria delle Grazie, which houses the Cenacolo Vinciano.
