That won't do anything. You want this:
db.table_name.picture.requires = RESIZE(200, 200)
Form.requires probably does absolutely nothing.
Your table name is 'test' and your field with the image is called 'pic' so
to adapt the imageutils.py example to your site would be this:
db.test.pic.requires=RESIZE(200,200)
