It should *just work*.  images (matplotlib.image.AxesImage) and
pcolors (matplotlib.collections.PolygonCollection) both derive from
matplotlib.cm.ScalarMappable.  This class implements an observer
pattern, and the colorbar registers itself with the ScalarMappable
instance.  If you change the normalization, or colormap, or
colorlimits, the ScalarMappable instance notifies it's observers, who
update automagically.

Let me know if you run into any troubles.
