you probably use php to call another (exec(),system() ect ) program to take the pic, something that came with the webcam

FYI, this is only possible to do from the web server via PHP code and executable. So if you need an end user to snap a picture of herself for uploading, you might try messing with flash instead.

Here is link that shows various *nix commands for capturing from a webcam.
