Try something like
gpg.exe --photo-viewer "C:\Path\Of\Viewer\viewer.exe %i" --edit mustermann
The %-escapes are:
%i is expanded to a temporary file that contains the photo.
%I is the same as %i, but the file isn't deleted afterwards by GnuPG.
%k is expanded to the key ID of the key.
%K is expanded to the long OpenPGP key ID of the key.
%t is expanded to the extension of the image (e.g. "jpg").
%T is expanded to the MIME type of the image (e.g. "image/jpeg").
%f is expanded to the fingerprint of the key.
%% is %, of course.
