I am not sure that how are you trying to make the screensaver. Is it through the windows explorer? If yes, then it will be a little tedious to get all the images that you want. One easy way can be selecting them from the photowell and copying them all to a common place form where you can pick them all for being used as a screen saver. Please, let me know if you are fine with this way or we will try thinking about something else.
