YUI Menus

Hi All,

Can anyone please tell me how to get icons for YUI menubar,
Say i have these menus:

| Home | About | Help | Forum|

these menus items are drop down,

I could get same icons for all the menus:
I added this code in style.css of the theme:

#yuimenu a.yuimenubaritemlabel {
background-repeat:no-repeat;
background-position: left;
background-image:url(Home.png);

}

but I need unique icons for each menu item,
Can anyone help me.

Thanks
