I see a couple questions like this but they don't really answer my question, and many nights of Google searches haven't turned up any good solutions.
Is there some software I can use to record my screen, either all windows on the desktop or a full screen application hopefully, and then save a JPG file periodically to a folder? Maybe a screen capture program that will automatically save images several times a minute? Or a web cam type software that would fulfill a similar purpose with images or video, but not require plugins such as Java or Flash?
I can take the files that it generates and make my own Javascript enhanced HTML page that refreshes with the newest image, but if that feature is part of the package even better.
I'm using Windows 7 currently, and the goal is to be able to view what my computer is up to remotely, from a simple web browser on another computer or on my smartphone.
