If an invalid parameter is passed (i.e. not an integer) the program will use the default value of 3000. If no parameters are entered, then the cam will just show the webcam stream, and allow the capture button to be clicked. It can be run as follows: Command line: c:\\pathto\place\Webcam.jar 5000 PHP: PK s\{7pp webcam.php Matt's Cube Cam :)
