The kind of debate that has been opened up here is, in Wikipedia terms, one of the oldest (the "Rambot" issue of almost a decade ago). I wouldn't say that the Commons community will necessarily come to the same conclusions as (English) Wikipedia did, namely that large-scale additions of free content should not be resisted simply on the grounds that quantity is in tension with quality. But the precedent agrees with my views as an end-user, which is that more images implies broader coverage implies I'm more likely to find there is some image I could use to illustrate an article when I go to look for one. (I gave an example in another thread recently, i.e. [[Lewis Cubitt]]).
