The Big Picture!

I am finally figuring out how to make my photos larger on my blog. I am also not happy with the redesign so I am redesigning the redesign. I figured since I haven't felt inclined to blog but am feeling like I want to redecorate, I might as well do that now!

The other things I would like to figure out:
1. how to center my post title
2. how to insert a line or a divider under it
3. how to insert a post divider object
4. I have figured out how to add extra blog pages but I'd like a better font on that tool bar under my banner. HUM. how to do that?
