From a shortcut in my startmenu.
Target: "C:\Portable Programs\emacs-26.0.91-x86_64\bin\runemacs.exe"
Start in: %HOMEPATH%
%HOMEPATH% is set to \Users\asc

I ran the following:
$ find.exe / -name libpng16-16.dll
/cygdrive/c/Portable Programs/emacs-26.0.91-x86_64/bin/libpng16-16.dll
/cygdrive/c/Portable Programs/inkscape/libpng16-16.dll
/cygdrive/c/Program Files/emacs-25.1-x86_64-w64-mingw32/bin/libpng16-16.dll
I found the old C:\Program Files\emacs-25.1-x86_64-w64-mingw32\bin on my
path, removed it and restarted Emacs, verified that it was not listed in
(getenv "PATH"), but no luck. I still cannot display PNG images.

Yes it does.
$ ./pngfix ../lib/python2.7/idlelib/Icons/idle_16.png
IDAT OK maximum 12 12 1070 2064 ../lib/python2.7/idlelib/Icons/idle_16.png
And finally, what is the value of libpng-version in your Emacs?

libpng-version
10634
Cheers
