Just a quick note, I was playing around with Google App Engine 1.3.5 with PIL 1.17 installed on my Windows 7 machine. Django Framework was complaining that the PIL module cannot be found from the system path when I was trying to resize an image using the Image module from Google App Engine. Since we call the Image module from Google App Engine and not using it directly, the only way to fix it is to uninstall PIL 1.1.7 and install 1.1.6 instead.
