Templates

I'm playing around with a couple of different looks for my blog.
I would like to have my own graphics on here at some point but
1.I'm not sure how to do replace what is there and
2. I am not feeling very creative right now.

Update: What a pain. I had to re-install the trackbacks and redo my side bar.
I guess I thought the new template would auto-absorb my stuff.
That's what I get for thinking I guess...haha.
I won't be doing that again for awhile.
