Can I use my Canon A520 as Webcam ?

I have digital camera Canon A520 ... and i was just curious can I use it as a WEBCAM ?

No, it does not have that function. None of Canons products have the option to function as a webcam. If you are interested in getting a webcam, Logitech has some that start as low as $30 but I like the QuickCam Orbit but it is rather expensive at $130 for a webcam but it's image quality is second to none.
