I'd been wanting to center my layout, but that means I have to slice my layout, and I hve NO idea how to do that.

can anybody please please learn me or point me to a good tutorial? I use PS

You can try this tutorial (you need Imageready, which should come with PS): http://www.absolutecross.com/tutorials/photoshop/basics/image-slicing/
Although it's not absolutely necessary to slice an image in order to centre a layout, depending on what it looks like it may make it easier
