List-style-image is a property / command to change the bullet of all elements with a display value of list-item. This includes not only li elements but any element with the display style set to list-item, specifically the li tag.

Example 1:

list-style-image: url(images/image1.gif);

This property indicates a graphic to be used for the list markers in the list structure. This should override the default appearance of list-markers in the current HTML list structure. If a 'list-style-image' is given a value of 'none' or the URL can not be loaded, the 'list-style-type' will be used in its place. The 'list-style-type' should always be specified in the event the URL pointed to in 'list-style-image' can not be loaded.
