I'd certainly draw into a NSBitmap and drag that around, using drag and
drop. The shadow is a bit trickier... if you have a standard shape for the
image, like the rectangular shape of cards in solitaire, you could just
make a bitmap with a shadow ramp on two edges (in Photoshop for instance).
You could then merge this into the bitmap you're producing for drag and
drop.
