I tried a couple of free programs that are supposed to capture on  a schedule.  However they want to capture video, not jpg's.

I've set up a Logitech 910 cam hooked to my computer and it points out the window towards the sky.  It was my intention to capture a picture of the sky each morning for a month or longer.

I can start the Logitech cam but then I have to manually start the capture.  Too often I'd forget to do that so I want a program that will start at a certain time and shoot a picture without me doing anything.

Just a single picture not a video.

Any suggestions or experience with something such as this would be appreciated.
