If you want to add a title to your xanga like mine, well first you have to make one, then you have to upload it so that you can use it, i use:
ImageShack
but there is also UploadImage.
Then you have to use this code and put it at the top of your custom header (unless you have a intro screen, then put it beneth this)
you can also if need to use this one, it will center it (only use this if your image is not automaticaly centered for you)
