This bit of code will let you change the opacity of an image using JavaScript; unlike most scripts it works on Safari and Opera as well as IE and Firefox. Simple send the id of the image and a value between 0 and 100 to change the opacity (0 being invisible and 100 fully visible).

function changeopacity( imageobject, opacity ) {

    
var object = imageobject.style;
    object.opacity = ( opacity / 100 );
    object.MozOpacity = ( opacity / 100 );
    object.KhtmlOpacity = ( opacity / 100 );
    object.filter = "alpha(opacity=" + opacity + ")";

}
