Notice that these two lines:
Field('image_file','blob'),
Field('image_upload','upload',uploadfield= Field('image_file','blob'))
should be
Field('image_file','blob'),
Field('image_upload','upload',uploadfield= 'image_file'),
or simply
Field('image_upload','upload',uploadfield= Field('image_file','blob'))
The blob should be created automatically.
