    How do i cahnge the image on this Cusor?

    Code:
    <div id="dot0" style="position: absolute; visibility: hidden; height: 11; width: 11;">
    <img src="bullet.gif" height=11 width=11>
    </div>
    <div id="dot1" style="position: absolute; height: 11; width: 11;">
    <img src="bullet.gif" height=11 width=11>
    </div>
    <div id="dot2" style="position: absolute; height: 11; width: 11;">
    <img src="bullet.gif" height=11 width=11>
    </div>
    <div id="dot3" style="position: absolute; height: 11; width: 11;">
    <img src="bullet.gif" height=11 width=11>
    </div>
    <div id="dot4" style="position: absolute; height: 11; width: 11;">
    <img src="bullet.gif" height=11 width=11>
    </div>
    <div id="dot5" style="position: absolute; height: 11; width: 11;">
    <img src="bullet.gif" height=11 width=11>
    </div>
    <div id="dot6" style="position: absolute; height: 11; width: 11;">

    Have you tried:

    Code:
    <style>
    <!--
    BODY{
    cursor:url("mycursor.cur");
    }
    -->
    </style>
    in the head?
