I can view JPG files but not PNG files on Windows and I don't know why.
I see that it's a configured feature in the output below but apparently
the right DLL is not included because
(image-type-available-p 'jpeg) => t
(image-type-available-p 'png) => nil
This is what my bin directory contains:
c:/Portable Programs/emacs-26.0.91-x86_64/bin $ ls lib* | grep "png"
libpng-config
libpng16-16.dll
libpng16-config
Cheers

Where did you get those PNG DLLs?

These three files are in emacs-26.0.91-x86_64.zip which I got from
https://alpha.gnu.org/gnu/emacs/pretest/windows/

How do you invoke Emacs from that installation?
Are there any other versions of libpng16-16.dll on that system?
Does pngfix.exe work (it should be in the same directory as
libpng16-16.dll)?
And finally, what is the value of libpng-version in your Emacs?

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
> Are there any other versions of libpng16-16.dll on that system?

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

Strange. I can only suggest stepping with a debugger through
init_png_functions, to see what exactly fails there and why.

I did a binary search of my config and found the culprit. Sorry for the
noise!
I had the following hidden away in one of the gazillion config files:
(add-to-list 'dynamic-library-alist '(png "libpng15-15.dll"))
Removing this file fixed PNG support for Emacs 26.
Again, I'm very sorry I didn't think of this any sooner.
