maps please

to those with keys, would it be possible to get overviews or even better Highres images of the maps delivered with the game? not all were covered in the battlereports so some guys not playing yet might, like me, be intrested in the other maps that are available already.

another thing is as far as i understood that blizzard reuses the map for diffrent setting games like one time with doodads on the chokes another without them what does it depend on and is it still called the same map? thanx in advance
