Need Online Manual for my computer webcam to solve issues

Before I started, I just want to introduced myself I am Dorothy and I have a cute webcam. And YES my problem is all about webcam, or Webcam Controller Software.
I really don't know why I cant find a manual for the software, oh well it is easy to use but then I need a manual. On the other hand, on the Webcam Controller screen with the Controls tab selected, I have seen or there is an icon that appears like a projector screen.
Once you click it, you can find a selection of pictures and you are able to add more. And that appears to be all you can do.
Right clicking, double-clicking and single-clicking appear to have no outcome.
