I've the same problem and now it's work with this tip : 
context.REQUEST.image.seek(0).

My xImageScale.py [external method] is :

def xImageScale(img_file, maxx, maxy):
   from PIL import Image
   from cStringIO import StringIO
   img_file.seek(0)
   im = Image.open(img_file)
   im.thumbnail((maxx, maxy), Image.ANTIALIAS)
   out_file_str = StringIO()
   im.save(out_file_str, im.format)
   out_file_str.seek(0)
   tmp=out_file_str.read()
   out_file_str.close()
   return tmp

You need to learn that you *MUST* provide a *FULL* problem description
when you seek help. This includes Error Type, Error Value
and Traceback in case you get an exception, and otherwise a clear
description what went wrong.

Hi David,

this is not the problem (tried it before).

The code
foo  = container.resize(context.REQUEST.image, size=size) # works nicely



at this point, try inserting:

context.REQUEST.image.seek(0)

foo  = container.resize(context.REQUEST.image, size=size) # 2nd time 
-error

does what you suggest. But it raises the same error.



cheers,
