I'm in the process of setting up a WordPress blog for the first time. I've managed to insert a custom header image (into the Default template), but the layout's gone a bit wonky. Originally it had a large margin/border around the image, and when I fixed the header tags to remove that, the image shifted over to the left. I can't figure out why this happened or how to make it properly centered again. Any help would be much appreciated!
