Simple code to show you how to display an image from a Web URL using the Tkinter Python GUI toolkit, the Python Image Library (PIL) and the data_stream created with io.BytesIO().

# optionally show image info
# get the size of the image

# put the image on a typical widget

I was able to install pillow 2.0.0 in Windows Python 3.3 using the exe installer and run this program.

Howver I can not get it to work under Ubuntu/python3.3 using source nor egg. Pillow appears to install and does announce [selftest.py] that JPEG support is available, but then there is a runtime error

builtins.OSError: decoder jpeg not available

Any ideas what I'm doing wrong ?

Verify Package: PIL.path
['/usr/local/lib/python3.3/dist-packages/Pillow-2.0.0-py3.3-linux-i686.egg/PIL']
