The code for the model UserImageStore is :
dal_db.define_table('UserImageStore',
Field('profile_image','upload',uploadfield='profile_blob'),
Field('profile_blob','blob'),
Field('upload_ts','datetime'),
Field('change_ts','datetime')
)
and the my show_image function is :
def show_image():
return response.download(request,dal_db)
