One question why is one banner in the center and one is on the bottom

.sorry make that two questions does if have anything to do with the banner size

Also image is not showing up on the our code part.
Fixed it so your image shows in the code part.
Images in a marquee always vertically align to the bottom.
Anyway this will fix the image on the right plus I fixed some other errors in the code.
