I'd guess it's 10400 or some such, which means you will need to install a newer version of libpng. See this portion of README.W32: PNG: requires the PNG reference library 1.4 or later, which will be named libpng14.dll or libpng14-14.dll. LibPNG requires zlib, which should come from the same source as you got libpng. Starting with Emacs 23.3, the precompiled Emacs binaries are built with libpng 1.4.x and later, and are incompatible with earlier versions of libpng DLLs. So if you have libpng 1.2.x, the PNG support will not work, and you will have to download newer versions. The latest pre-compiled binaries don't support versions of libpng older than 1.4.0.
