That is because the directory Lib/site-packages/PIL is in sys.path, so
any PIL module can be imported directly without the PIL prefix. (The PIL
dir is added to sys.path by the file Lib/site-customize/PIL.pth.)

In the above usage I would say PIL is a directory containing a
collection of modules. But PIL is also a package, since you can say
from PIL import Image
