I'm far from great with technology, but can my camera (Samsung S600) be used as a webcam, and if so, how would I go about doing that?

EDIT: Alternatively, I have a PC Line webcam, but I can't find the installation dsk for it, can it still be used because it's not registering on my pc?

BTW this is for use over MSN.
Funny words.

Probably, but don't expect the batteries to last long.

Go into set-up, or whatever, there might be an option to switch between PC settings. As in, whether it works in storage device mode or in webcam mode.

some can, some cannot.

my cheapo $40 can double as a webcam but my $400 Sony cannot.
