Hanoi Rocks-Bangkok Shocks, Saigon Shakes, Hanoi Rocks
I picked this one not so much for itself, but for the style it represents. That is a live picture on the cover of a studio album. Doesn't happen that often and seemed to happen more on punk albums than in metal in hard rock. Others include Soundgarden-Louder than love, Acid King-3, the Nuge did it on more than one occasion. There are others as well and a number were in the 1980's. I don't know the reasoning behind any of these covers, but for some reason someone saw a live photo as being more fitting than bringing in artist to do a drawing or painting.
