The sample scripts (provided in the Scripts subdirectory) make some
bold assumptions on what kind of images you'll run them with.  The
following info might help you avoid incomprehensible error messages:

script		comments
viewer.py	display an image; should work on any image mode.
		note the improved Tkinter interface, and also the
		special treatment of 1-bit images.

enhancer.py	illustrates the ImageEnhance module; use on
		a truecolour (RGB) image for best effect.

thresholder.py	illustrates a dynamically updated 1-bit overlay; only
		works properly on greyscale images.

painter.py	illustrates selective update of a image canvas;
		use on a truecolour (RGB) image for best effect;
		may crash if you move the brush outside the image
		(due to "undefined behaviour" in the "crop" method)
And yes, they all require that you have compiled Tk with the PIL
interface (tkImaging.c).
