I remote login into my Pi using TightVNC Viewer. Now I can see Pi GUI. But when I do `raspistill -o 0.jpg` I can't see the display of the picamera?

Why is the picamera stream not visible in TightVNC? Is there some settings I have to change on Pi to allow the camera to be streamed to Remote desktop?

Alternatively I have been able to use [this][1] but it works very slow and there is very much things to be improved. What options do I have to see the stream of the picamera?
