$ sudo apt-get install libjpeg8-dev

Then find libjpeg.so and create link on /usr/lib/
$ find /usr/lib -name libjpeg.so
/usr/lib/arm-linux-gnueabihf/libjpeg.so
$ sudo ln -s /usr/lib/arm-linux-gnueabihf/libjpeg.so /usr/lib/

Then install PIL and python-imaging-tk
$ sudo apt-get install python-pip
$ sudo pip install PIL
