I posted a question before regarding this subject, and read other ones posted before, but none has successfully solved my problem.
I am trying to install PIL on Mac
Worth noting and good information to have whenever working with Python and PIL: If you use virtualenv (and I think it's a very good idea), PIL may not correctly detect the image libraries on your system and install without JPEG/PNG support. Use the pillow package for a compatible PIL fork that finds them correctly.
