I'm trying to send a picture to the back, but it is not moving.
I've tried creating a new spread sheet first with the picture and then again
with the spread sheet first and it will not let me set the picture to the
back.

I've tried many pictures and 4 different machines including a Mac.
I can bring the spread sheet into word and do it there, but that means I
have to recreate the spread sheet everytime I change any of the cells.

Thank you,
Mike
