Repeating background images
 

I added a background to an Excel spreadsheet. Unfortunately it repeats the
image all the way to the bottom of the worksheet, making a 30K document about
3MB in size. How can I have it only display the image once immediately behind
my content without repeating? If I cannot limit that, is there a way to force
the worksheet to be only 100 rows long and 15 columns wide, eliminating the
repetitive images simply by reducing the "physical" size of the worksheet?
