as soon as I put in custom modules on my xanga the picture at the top stopped being centered. why did it do that and how can I make it go back to the way it was? my xanga (http://www.xanga.com/thegirlwhokilledyourbaby)

The header looks centered to me.

well on my computer when it first opens its centered but then when it fully loads it moves to the left some.

i guess its my computer cause i asked a lot of people and everyone said its in the center...oh well
