MAC SOFTWARE TO SCHEDULE WEBCAM PICTURES THEN UPLOAD TO DROPBOX?

I have very little experience with apple products since I use a PC and android phone primarily but I have a mac mini with a logitech webcam attached and want to be able to shedule pictures to be taken on a timed bases (ever x minutes, x hours, OR at scheduled times such as 9:15AM, 9:30AM, 9:45 AM, ect) then be able to automatically upload them to drop box. Is this possible on mac? If not, is it possible on windows 8.1?

Thanks for any help.
