I think your line numbers are off by one, because I'd think it is the  
getattr that would be causing the Attribute Error (at most, line "9"  
could give an attribute error for something called "data".

Zope turns file upload objects into   
ZPublisher.HTTPRequest.FileUpload instances. and pass them to your  
method. FileUpload instances have an interface similar to python file  
objects, you can .read(), .seek(), .close() or do whatever you want  
to them and might not need to wrap the contents into a StringIO  
object first. (your trying to fetch the file as an attribute of  
"self" seems to imply that you think the form data is already  
uploaded into zope and is an Image object in a folder. It isn't there  
yet, and won't be unless you store it there.)

I think if you removed lines 8 and 9 (by your numbering) and renamed  
the second argument to the method to "original_file", things would  
work as you need:

1 def makeImages(self, original_file):
2
3    import PIL.Image
4    import PIL
5    import os.path
6
