ok you asked for it! My personal webspace is currently dead so I'm afraid its a cut-n-paste job:
This is method1 - without an extra <span> tag.
The alternative is to use the 2nd method on this site:
http://wellstyled.com/css-replace-text-by-image.html
This makes the image a link, but I still can't get the nested <ul> to show.
sorry for wearing out your mouse scroll wheel with this wodge of code:
