This is the original Cover of the Herzeleid Album, which led some to accuse Rammstein of being Nazis. It is not clear, though, what unsightly bare chests would have to do with right-wing extremism. Maybe this was just put forward as a smokescreen for the reason that people think they are Nazis to divert attention from the real reasons. A coworker says it looks more like the Village People than Nazis.
If I am not mistaken the other side of the CD jacket is in the Nazi colors, which is more suggestive of Nazism than them simply not having shirts on. The Rammstein disinformation mill seems to be at work in the story that this image is the source of the accusations of Nazism.
