CSS Property - List Style Image
Value: <url> | none
Applies to: elements with "display" value "list-item"
Percentage values: N/A
This CSS property sets the image that will be used as the list-item marker. When the image is available it will replace the marker set with the "list-style-type" marker.
Using "list-style-image" instead of using the default setting has its downfalls. You can not position the image exactly, the image is placed where the default style is, disc, square etc...
