Objective:
Create two buttons that will change the WordPress custom background image on the fly.
Requirements:
- The function must be available for any user of the site.
- Onclick button '1' must display image 'a.' If the image is already displayed, the button shouldn't do anything when clicked again.
- Onclick button '2' must display image 'b.' If the image is already displayed, the button shouldn't do anything when clicked again.
I have tried using JavaScript following the tutorial at the codebelly site: http://www.codebelly.com/javascript/backimagechange.html, but it does not work.
I'm a newb (css/html only). Can someone provide a step-by-step instructions on how to accomplish this?
