Create a Python Script with the attached content in your root folder and
call it through the Web.  It will 1) change the default engine to PIL for
all Photo Folders, 2) change the engine of all Photo objects to PIL, and 3)
purge all the cached displays created by ImageMagick.

It has been a while since I've used this.  Let me know if you have any
problems with it.
