Underneath the volume control is a right corner symbol with an arrow.
Just click it and you'll get a full screen image.

Subject: [teacherartexchange] Windows Live Messenger and Web Cam
I've got Windows Live Messenger and a Web Cam. When I open it and I'm
chatting with someone, their image is very small. If anyone knows how
to enlarge the video screen...please write me.
Yahoo Messenger will enlarge the image and fill the screen if you just
double click it...but I have other problems with Yahoo Messenger, so we
don't use it.
