[Image-SIG] Creating a Transparent Image and Placing it Over Another Image (txt)

[Fredrik Lundh]

The Tkinter module contains a "Image" class, so doing the "import *"
thing after all other imports will stomp out the Import module.
Either fix all uses of PIL to use fully qualified names (replace
"import Image" with "import PIL.Image", "Image.open" with
"PIL.Image.open" etc), or, easier, move the "from Tkinter import *"
line to the top of the imports.
