I made something in Excel and I need your help again.

I essentially made a very large 'march madness' style bracket in Excel 2007. Now, how do I save it as a picture? I tried saving it as a PDF, but it split it into pages. I can't have that. How do I tell it to save it as one giant-paged PDF? Or, even better, one giant sized JPG/PNG?

Heppel! Heppel!
