How can I use Sony Digital Camera DSC-S600 as Web camera?

I want to use my digital camera as web camera to chat with my friends, is this possible, should I install some software ?
or how to set this up ? pls advise

that actually doesn't work as a web cam
even if u install some external software what happens is that the camera's lens will remain closed and go to mass storage mode to access ur memory stick and ultimately u can't do that
