Thank you Arif.
Yes I agree it does break up the symmetry, I believe it is because of the newer wide screens that it doesn't fit, mine is 22" so I have my page adjusted so that it fits perfectly. Dave gave the size 1200 X150 pix for us to do, then it was suggested by a couple of members that we do 1500 X 150 pix, which I now do, but I still have quite a few banners that will be posted in the smaller size.
