photo in gpg key

[vedaal]

am using 1.07 Nullify r-2 on windows 98

have added a photo to a key without any problems, but get the following
error message when wanting to display the photo:

1.07 was installed using the Nullify installer
is there any special command necessary to create/specify a directory for
temp files?

TIA,
