Thanks!  Some seem to work and perhaps some not.  This may give us some clues

Roy,
I was able to get an image using the following query.  The image 
looks fine although I am not sure how many elements along time, 
elevation, x, and y are included in the image because I don't know 
how to save it into a file (the image was displayed in my browser).
