Help!

So, I came up with this^ really awesome header (don't ya think?) :) and it doesn't fit right. I mean, it blows up to big, and I can't figure out how to shrink it to fit.

Does anyone have any information that might help?

If so, I would reall appreciate it!

Our new blog header!

I've recently been working on our computer, learning new things about editing pictures, adding text, fixing the color, etc. Well, I've learned how to make one of our pictures into a header for our blog, BUT, I can't find out how to get it up on the blog!! (very frustrating I'll tell you... :))

So my questions are,
Does anyone know how to make it into our header???
Have you done this before?
Is it very hard to do??

In other words....
....Any tips would be well appreciated!!
