MS Windows:

   $ strings emacs.exe | grep png
libpng12d.dll
libpng12.dll
libpng.dll
libpng13d.dll
libpng13.dll

But 'depends.exe' show that 'libpng12.dll' come from third party:

   c:\opt\graphviz2.26.3\bin\LIBPNG12.DLL

Emacs from ftp.gnu.org is come only with 'libXpm.dll'.

With 'grep svg' on Windows:

   $ strings emacs.exe | grep svg
librsvg-2-2.dll

I download 'librsvg-2-2.dll' from
http://ftp.gnome.org/pub/gnome/binaries/win32/librsvg/2.22/

and put it to PATH. Emacs on open .svg say:

byte-code: Cannot display image: (Invalid image type `svg')
image-type: Cannot determine image type

Linux:

   $ strings `which emacs` | grep png
libpng12.so.0

For

   $ strings `which emacs` | grep svg

no match. Need upgrade Emacs to 23.x from 22.2.

So try search svg string in emacs executable and install appropriate lib.
