Add a call to capture() above the os.system() call. For example:

camera.capture("Ring %s.jpg" % time.strftime("%Y%m%d-

%H%M%S"))

The full Python script should look like this:

import RPi.GPIO

import os

import picamera

import time

RPi.GPIO.setmode(RPi.GPIO.BCM)

RPi.GPIO.setup(2, RPi.GPIO.IN,

pull_up_down=RPi.GPIO.PUD_UP)

camera = picamera.PiCamera()

def Ring():

camera.capture("Ring %s.jpg" % time.strftime("%Y%m%d-

%H%M%S"))

os.system("mpg321 ring.mp3")

while RPi.GPIO.input(2) == RPi.GPIO.LOW:

pass

while True:

if RPi.GPIO.input(2) == RPi.GPIO.LOW:

Ring()

The string passed into strftime() determines the format of the

date and time string. For more information about the time

module, see http://docs.python.org/3/library/time.html
