Um.

I suspect he's double counting somehow.
A month ago there were only 492,308 *total* image pages on enwiki.

Ditto for his fair use numbers.. about 2x reality from my last
measurements. The commons total looks about right.

I welcome anyone interested in running stats to contact me for a
sanity check on their queries... there are a number of common pitfalls
like  counting directly from the category tables, and failing to
filter for distinct or assuming images will never have a free tag and
a fair use tag at the same time... that can cause incorrect results.
