    If you are meaning an automated way, I'm not sure. Manually, if you have the screen on view you can press PrtSc to take a snapshot.

    I know ffmpeg can do it from video. You need a guru in this. I can your mutli-media working, but I'm not expert at what you require.
    @microchip or perhaps @oldcpu may offer help. Wait it out.

    Yes, ffmpeg can capture both from /dev/video and from a rectangular area of the screen.

    ffmpeg has a switch for rate:

    ffmpeg .... -r 24 ....

    I wonder whether setting a very slow rate will create a film, something like this:

    To capture from webcam:

    LD_PRELOAD=/usr/lib64/libv4l/v4l1compat.so ffmpeg -s 640x480 -r 1/60 -sameq -f video4linux2 -i /dev/video -f oss -i /dev/dsp ~/b.mpg

    To capture from a rectangular area:

    ffmpeg -f x11grab -s 640x480 -sameq -r 1/60 -i :0.0+62,207 -sameq ~/a.mpg



    The 1/60 is the capture rate, 1 frame in 60 seconds.

    This will create a film, not a sequence of images, but maybe this is what is required by OP.

    A sequence of images can also be created by the ffmpeg.

    From the mpg film, a sequence of images can be extracted by ffmpeg.

    Probably I wasnt so clear. I'd like to save image every 1 minute from website (from webcam but not my own) So I have something like[EDIT] and every minute is the picture on webpage updated - and I want to save all the pictures, of course with unique names.
