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'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.
