Dan, Put a print statement like so above the line: original_file=StringIO(original_image.data) that reads: print type(original_image.data) And let us know the results of the iteration on which it fails. ... passing something "wrong" into StringIO seems to be what's breaking your code. ----- Original Message ----- From: "Dan Shafer" <dan@gui.com> To: "Chris Withers" <chrisw@nipltd.com> Cc: <zope@zope.org> Sent: Monday, February 18, 2002 12:06 PM Subject: Re: [Zope] System Error from Zope Book Example

Can you paste the code from Thumbnail.py here?
(specifically, lines 10-20 ;-)
Sure. Sorry. I had done this in my original message and in an effort to conserve bandwidth I guess I made it harder for people to help.
Sigh.
Here's the code; I've eliminated the docstring so the first executable line in the function appears on line 10 of the original code.
def makeThumbnail(self, original_id, size=128)
from PIL import Image from cStringIO import StringIO import os.path
# create a thumbnail image file original_image=getattr(self, original_id) original_file=StringIO(original_image.data) image=Image.open(original_file) image=image.convert('RGB') image.thumbnail((size,size)) thumbnail_file=StringIO() image.save(thumbnail_file, "JPEG") thumbnail_file.seek(0)
# create an id for the thumbnail path, ext=os.path.splitext(original_id) thumbnail_id=path + '.thumb.jpg'
#if there's an old thumbnail, delete it if thumbnail_id in self.objectIds(): self.manage_delObjects(thumbnail_id)
# create the Zope image object self.manage_addProduct('OFSP').manage_addImage(thumbnail_id, thumbnail_file, 'thumbnail_image') thumbnail_image=getattr(self, thumbnail_id)
# set the 'original_id' property thumbnail_image.manage_addProperty('original_id', original_id, 'string')
cheers,
Chris
