Yup.  You can use PNG too for 24 bit images.

But in the case of the US states example, think about what you can do with
color: each mouse state (over, down, click, active, disabled) can be
communicated using color and a single draw object.  You could also overlay
draw objects on top of a rendered US image, so that each state hilites
independently.  With 50 (or so) state objects, a little scripting could go a
long way.  Just a thought...
