TileCache : Cannot Identify Image File

On a newly set up CentOS box, and newly installed TileCache, i got this:

Last lines says:

File "/usr/lib64/python2.7/site-packages/PIL/Image.py", line 2030, in open
    raise IOError("cannot identify image file")

I tried replacing PIL with Pillow but still got an error. I had successful installations on other CentOS boxes before, so PIL should work. After removing Pillow, I reinstalled PIL... then, that's it! It worked! Must have had an issue when I installed PIL the first time.

Solution:

        Reinstall PIL:
               install pip
                        # sudo yum install python-pip

               uninstall PIL
                        # sudo pip uninstall PIL

               reinstall PIL Imaging

                        # cd Imaging-1.1.6
                        # sudo python setup.py install
