Django ImageField validation error caused by incorrect PIL installation on MAC

I kept getting a validation error in the django admin pages while trying to upload an image. The validation error said:

Upload a valid image. The file you uploaded was either not an image or
a corrupted.

I really broke my brains on this one but finally got it to work! I knew for sure that the image was not corrupted so it had to be something else. After some googling I found a couple of pages on the Python Imagina Library and how it was kinda difficult to get that installed properly on MacOS. When I first installed Django I just used the standard “python setup.py install” command for installing PIL, but that did not install it correctly.

What worked for me was the following:

1. Install the Apple XCodeTools (Either from the MacOS X install CD or register and download them here)
2. Install the libjpeg for JPEG support by downloading the source here. Extract the downloaded file and move into the directory (most likely called “jpeg-6b”). Then type:
   cp /usr/share/libtool/config.sub .
cp /usr/share/libtool/config.guess .
./configure –enable-shared
make
sudo mkdir -p /usr/local/include
sudo mkdir -p /usr/local/bin
sudo mkdir -p /usr/local/lib
sudo mkdir -p /usr/local/man/man1
sudo make install
3. Now for correctly installing PIL: Download it here. Unpack it and change the setup.py file:
   Change:
   JPEG_ROOT = none
ZLIB_ROOT = none
   to
   JPEG_ROOT = “/usr/local/include”
ZLIB_ROOT = “/usr/local/include”
   then run
   python setup.py build_ext -i
python selftest.py
sudo python setup.py install

That should be it! Hope that helps anyone!
