just a guess, but i don't think getattr is returning what you think it is 
returning.

The image has not been 'stored' anywhere yet, it is just a FileUpload 
instance.  To get at the information in this instance:

# the var name used in your form is misleading, it is not just the image id
fileName = self.REQUEST['original_id'].filename
fileData = self.REQUEST['original_id'].read()
