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.
