Put A Head On A Different Body With Picnik Putting A Head On Another Body.?

Putting a head on another body.? - put a head on a different body with picnik

I have a new PC (Vista) and old free program that works with my old printer, which normally was not compatible with Vista now. was a big thing. This program is not already available on the Internet. My grandchildren had a really good time with him. All I want is to be able to put his head in a different location. nothing more. Most software that I have found, are full of things that you never use and do not want. Suggestions?
