Tk::WinPhoto for ActiveState
As puploki have already said, the Tk::WinPhoto module belongs to the Tk distro.
The latest (precompiled) Tk ppm package is available at the bribes repository (you can include it (together with many others) in your local ppm repositories list through PPM::Repositories).
But unfortunately (and strangely), despite the above mentioned Tk ppm package is in synch with the latest Tk version available on CPAN (804.027 at the time of this writing), it does not include the Tk::WinPhoto module. I can just guess that this is because Tk::WinPhoto does not work properly or it even does not compile on Windows (in the ppm Tk POD it says that Tk::WinPhoto is considered an experimental module).
