putpixel is a method of the Image class, and it's documented
along with all other methods for that class:

http://www.pythonware.com/library/pil/handbook/image.htm

(also see nick bower's post)

as other have pointed out, it's much more efficient to do "bulk
updates" via putdata and/or fromstring...  (to update a subregion,
you can create a new image and paste it into the original).
