HTML PROBLEM - how do i change the image of a bullet point?

[amie]

i'm a html novice and i'd like to know how i can create an unordered list using bullet points where each one has a different url image (image from the web). so for example, the first bullet point can be a picture of an apple, the next a pear etc...i've tried using a style sheet but all i can manage to do is get bullet points which each have the SAME image (e.g. they all come up as images of apples). is a style sheet even necessary for this? any one have any ideas? thanks in advance
