We have been using a webcam to take the pictures as the receptionist can take the picture and it is immediately available to use.
Unfortunately, most (all) of the cameras are not set up to produce a square picture that AC requires (if no distortion).

So after you have the webcam picture now you have to crop it to a square format to prevent distortion.

It would be nice if they had the pictures in a more common format, 4x3 = 640x480 = VGA.
