GEOJSON Podmiana domyślnego markera + rotation

[BIMSON]

Wszystko jest tu:
http://docs.openlayers.org/library/feature_styling.html

Zgodnie z przykładem i example'm który znalazłem chciałem zacząć od zmiany markera. Ale nadal wyświetla mi się domyślna kropka. Mój kod wygląda tak:

Kod:

vectorlayer = new OpenLayers.Layer.Vector("geojson",{
                    
                    strategies: [new OpenLayers.Strategy.Fixed()],                
                    protocol: new OpenLayers.Protocol.HTTP({
                    url: "new.php",
                        format: new OpenLayers.Format.GeoJSON()
                    
                    }),
                                        // parametry opcjonalne
                    displayInLayerSwitcher: true,
                    
                    
                    
                },{
                    styleMap: new OpenLayers.StyleMap({
                        "default": {
                            externalGraphic: "icon.png"
                            //graphicWidth: 17,
                            //graphicHeight: 20,
                            //graphicYOffset: -19,
                           // rotation: "${angle}",
                           // fillOpacity: "${opacity}"
                        },
                        "select": {
                            cursor: "crosshair",
                            //externalGraphic: "foto/icon/icon.png"
                        }
                    })
                });
    
map.addLayers([gphy, gmap, ghyb, gsat, vectorlayer]);
