Hi Johan,

Okay, this sounds like your version of PIL or Pillow is missing a decoder 
needed for thumbnail generation to work.

First, can you verify which you're using? You can look to see if a PIL or 
Pillow directory is in /usr/local/lib/python2.7/dist-packages/.

Also, do you use homebrew? On MacOS X, there's a couple different ways to fix 
this, so I want to make sure I give you decent instructions.

Pillow is the modern replacement for PIL, and is easier to install and get 
running. If you're using PIL, we'll probably have you uninstall it and install 
Pillow in its place. However, we'll need to make sure you have a couple of 
libraries installed first, to ensure it has this decoder.

Christian
