html image rendering not working Win Emacs 24.4 (eww and gnus)

[Sivaram Neelakantan <nsivaram.net@gmail.com>]

I upgraded to the stock install of GNU Emacs 24.4.1 (i686-pc-mingw32)
of 2014-10-24 and now the image rendering has stopped in gnus(shr) and
eww.  This used to work in Emacs 24.3. And here is some of the
settings that I picked up from my .Emacs and vars.  I believe the
dynamic-library-alist is picked up from ezwinports bin directory.

dynamic-library-alist is
