The list-style-image specifies an image for the marker rather than a bullet point or number. You can try to run the following code to implement list-style-image property:
Example
<html> <head> </head> <body> <ul> <li style = "list-style-image: url(/https/www.wsxdn.com/images/bullet.gif);">Karnataka</li> <li>Hyderabad</li> </ul> </body> </html>
