How do you put laptop webcams on your laptop?

Usb style plug into your Usb slot. The rectangular slot that all pcs' have.

If it came with a disk you may have to install some software.
Most new cams are "plug n play" .
You need to be in a program that rrequires it to activate however. Like skype or msn,
If you just plug it in most do not display.

Let me know how you go.
