I take that back.  The precompiled binary from the 23.2.90 pretest on
alpha.gnu.org doesn't display PNG, either.

This is consistent with what Drew sees: none of the precompiled
binaries, including those of Emacs 24 snapshots, can display PNG.

So, Sean, please try to debug this on your machine, because the
binaries I build here don't have that problem.  For starters, where
(from what archive of which package) did you get the PNG headers?
