I couldn't find old versions of the DLLs somewhere on the ezwinports
sites? (I looked for an "Old Releases" folder that sourceforge sites
sometimes have, but couldn't find it).

So what I did was to install emacs 24.4 (emacs-24.4-bin-i686-pc-mingw32)
from here:
 http://ftp.gnu.org/pub/gnu/emacs/windows/

For 24.4 from above:
 libpng-version's value is 10612
 libjpeg-version's value is 90

Then I copied in the entire bin directory contents of the unzips pf
these ezwinports packages into the emacs-24.4-bin-i686-pc-mingw32/bin
directory:
 gnutls-3.3.11-w32-bin.zipgnutls-3.3.11-w32-bin.zip
 jpeg-v9a-w32-bin.zip
 libpng-1.6.12-w32-bin.zip
 libxml2-2.7.8-w32-bin.zip

And now PNGs display fine inlined in Gnus, and JPEGs probably will as
well, when I encounter them, because:
 (image-type-available-p 'jpeg)
 (image-type-available-p 'png)
both returns t.

Thanks, Eli!

Found it as lisp/term/w32-win.el on 24.3 (ie. uncompressed) and as
share/emacs/24.4/lisp/term/w32-win.el (also uncompressed) on 24.4.

Thanks!
