What does this produce in Emacs:
M-: (image-type-available-p 'png) RET
My guess is it says "nil", which means you don't have PNG image
support in your Emacs.
In a nutshell, don't mix a native Windows build of Emacs with Cygwin
libraries -- that will never work. Even Cygwin Ghostscript could give
you trouble, when used from a native Windows Emacs.
If you want a Cygwin environment, install a Cygwin Emacs. If you want
a native Windows environment, install native Windows image libraries
(see the file README.W32 for URLs) and a native Windows build of
Ghostscript.
