Once a poll is generated it takes 10-15 minutes sometimes for it to show up on the thread. This occurs every time a poll is posted and is just an idiosyncrasy of the board... I would think most would know this by now.

D. Change Viewing Angle

You do this first to determine if the pattern in the image changes due to reflections.
