I didn't want to do that because of what is said in the following article:
http://css.maxdesign.com.au/listutor...troduction.htm
"HTML bullets can be replaced with graphic images using "list-style-image". However, the placement of these images is inconsistent across most modern browsers. There is also very little control over how the bullets appear beside the list items."
That's why I almost always use non-repeating background images.
Best regards,
Christian
