Custom Bar Towels How Do I Make A Search Bar For My Web Site Using My Own Custom Image?

How do I make a search bar for my web site using my own custom image? - custom bar towels

I have this tutorial http://megatutorials.blogspot.com/2007/04/stylish-search-bar.html
shows you how to make your own search bar, but how can it really? If you already have a design coded in ImageReady with my own search bar, how can I know if it works (http://brandyweb.net/wordpress example)?
