What is the syntax of the photo-viewer parameter?
i tried the following:

gpg.exe --photo-viewer "C:\Path\Of\Viewer\viewer.exe" --edit mustermann 
showphoto quit

and gpg says:
gpg: this platform requires temporary files when calling external programs
gpg: unable to display photo ID!

As you can see i'm running it on a windows system!
