Well-explained, but I would like to add: the lower field is clearly labeled "alternate cover". The definition of alternate, as used here, is "a substitute; an alternative; one designated to take the place of another". The group shot cover was designed specifically to replace the original, controversial cover, as the referenced commentary in the article clearly describes. This makes the group shot unquestionably the alternate cover, even if it is more common/recent. The same goes for albums like Light a Fire and Yesterday and Today. So no matter whether we can assert/prove which version is more common, it is blatantly obvious which cover is the "alternate". Indeed, the controversy caused by the original cover, and the subsequent switch to the alternate, is the entire subject of the article's commentary. How there is even a question of which image belongs in which field is absolutely boggling to me.
