You override displayClass, e.g.:

   var zbo= new OpenLayers.Control.ZoomBox(

     {title:'Zoom Out by clicking or dragging a rectangle.',

     out: true,

     displayClass: "olControlZoomBoxOut"});

And in a style you set something like:

 .olControlPanel .olControlZoomBoxOutItemInactive {

    width:  24px;

    height: 22px;

    background-image: url("../graphics/zoomout.gif");

 }

 .olControlPanel .olControlZoomBoxOutItemActive {

    width:  24px;

    height: 22px;

    background-image: url("../graphics/zoomoutX.gif");

 }
