When you define the field, you can do:
Field('avatar', 'upload', requires=IS_IMAGE())
or after the tables have been defined:
db.auth_user.avatar.requires = IS_IMAGE()

After the tables have been defined, you can do:
db.auth_user.first_name.requires.append(IS_ALPHANUMERIC())
That adds the validator to the existing IS_NOT_EMPTY validator.
However, I wouldn't use that validator for names because it doesn't allow
valid name characters such as spaces, hyphens, and apostrophes. Anyway, if
you prevent fake names with special characters, those users will just
create fake names with alphanumeric characters, so either way you don't
have a real name.
