[vtkusers] dimensions of image

[Amy Squillacote]

Also you need to update the pipeline before you call methods like 
these.  The values you're getting back are the default values before the 
pipeline executes.  Try calling reader->Update(); at the very beginning of 
your SetupCamera() method (just before vtkImageData* image = 
reader->GetOutput();).
