Thanks for the offer, but I found out what my problem was. It was PS related. I was creating an image exactly the size I needed, and placing a drop shadow. The shadow wouldn't line up. So I created an image 3 times the height of what I wanted, layed down the colors, etc, and the drop shadow. I then went and cut out the center of the file, and made that my tile, and the image tiles perfectly. Funny I couldn't find a tutorial or mention of the problem anywhere. Did feel nice to solve the problem myself though.
Anyway, thanks again to all for offering up help.
