Where's that space coming from?

I am confused... I created this page:

http://sarahpellerdesign.com/shannon/index.html

And then I created this one:

file://macintosh%20hd/Users/sarahpeller/Art/sarahpellerdesign/site/sha nnon/sound%20with%20menu.html

And there is a space between the nav bar and the image below on the second page, but not the first.

Anyone know why this might be?
