Thanks Alexa and Jerzy.
other questions? ... Here they are:
- changing to an image grey scale only needs ... what?
- I need to do a 'plane fit' of the image. Does matplotlib
have some routine for this? Or shall I use other math libs?
Thanks again.

Cloud computing makes use of virtualization - but cloud computing
also focuses on allowing computing to be delivered as a service.
