What you need to keep in mind is that there is only a certain number of pictures that they can take from different angles. It's not like a console or PC game that you install with a DVD and the pictures are rendered on your system. If they had a camera shot for every possible angle of approach, the game would be a monster and you wouldn't be playing it online, with no client download..... for free!! Having said that... when you find an angle that does not give you ANY information about the shot, right click and submit a bug report. It's the easiest way to get the developers attention. I know there are certain places (#5 left of the pin near the edge of the green) where the forward view is useless, but like ncvis said, go to the reverse angle, it usually gives a better read anyways.
