IIRC, libpng comes with Visual Studio projects to build shared
libraries (dlls).  You can use them to build libpng12.dll and zlib.dll
from source code on Windows.

See example.c in the sources directory.  Reading libpng.txt might be
of help too.

Hm... what's wrong with using GDI+ directly?  I remember I have used
it to display PNG images w/o any trouble.

Anyway as long as you use C++ you might find it more convenient to use
a C++ wrapper around libpng, png++:

(just a bit of fair, I hope, advertisement (-: )

You might if you want to... :-)
