Is that what you meant? Making an actual "button" on a webpage is something entirely...well...just different but more involved.
Thanks for your reply. I have the graphic, it's on my hard drive. In short, intead of clicking on a text link, such as I have now on my blog, on a couple of links I'd like the picture to be the the "click through."
