When Raspberry Pi is using a HDMI-VGA adapter is necessary to add an extra configuration in config.txt file (It must be located in boot partition directory but If it does not exist you need to create it). Add next lines at the begining of the file.

This setting will force a screen size of '''1024x768 60 Hz'''. Although the screen does not support the new setting will work.

You have to re-install PIL and also install the needed libraries as well as link them manually. This answer is based on this blog post for a regular ubuntu PIL installation and this askubuntu question, where it is explained how to compile the jpeg encoding:
### uninstall PIL
sudo pip uninstall pil
### download and compile the JPEG library
wget http://www.ijg.org/files/jpegsrc.v8c.tar.gz
tar xvfz jpegsrc.v8c.tar.gz
cd jpeg-8c
./configure --enable-shared --prefix=$CONFIGURE_PREFIX
make
sudo make install
### link the libraries correctly - RASPBERRY PI ONLY
sudo ln -s /usr/lib/arm-linux-gnueabi/libjpeg.so /usr/lib
sudo ln -s /usr/lib/arm-linux-gnueabi/libfreetype.so /usr/lib
sudo ln -s /usr/lib/arm-linux-gnueabi/libz.so /usr/lib
### install rest of the libraries, as well as freetrype and zlib
sudo apt-get install libjpeg-dev libfreetype6 libfreetype6-dev zlib1g-dev
### re-install PIL
sudo pip install pil</nowiki>
