If GTK 2.0 is installed, addpm will arrange for its image libraries
to be on the DLL search path for Emacs.
+ For PNG images, we recommend to use versions 1.4.x and later of
+ libpng, because previous versions had security issues. You can find
+ precompiled libraries and headers on the GTK download page for
+ Windows (http://www.gtk.org/download-windows.html).
+
+ Versions 1.4.0 and later of libpng are binary incompatible with
+ earlier versions, so Emacs will only look for libpng libraries which
+ are compatible with the version it was compiled against. That
+ version is given by the value of the Lisp variable `libpng-version';
+ e.g., 10403 means version 1.4.3. The variable `dynamic-library-alist'
+ is automatically set to name only those DLL names that are known to
+ be compatible with the version given by `libpng-version'. If PNG
+ support does not work for you even though you have the support DLL
+ installed, check the name of the installed DLL against
+ `dynamic-library-alist' and the value of `libpng-version', and
+ download compatible DLLs if needed.
