I'm new with using CSS and Java for drop downs. I'm using images and text in my nav and I can't seem to get the CSS right. In Firefox my height is all wrong on my images and in IE 7 my text drop downs seem to jump. Can someone please send me some advice.

Thanks Guys

LOL I think I fixed part of my problem. But now I have white spaces between my nav bars. But this only shows up in IE. So I still need some help.
