GEOJSON Podmiana domyślnego markera + rotation

[BIMSON]

To nic nie dało.
Teraz mam tak :

Kod:

var s = new OpenLayers.Style({
  pointRadius: 10,
  externalGraphic: "icon.png"
});
    vectorlayer = new OpenLayers.Layer.Vector("geojson",{styleMap:s},
                
                {
                    strategies: [new OpenLayers.Strategy.Fixed()],                
                    protocol: new OpenLayers.Protocol.HTTP({
                    url: "new.php",
                        format: new OpenLayers.Format.GeoJSON()
                    
                    }),
                                        // parametry opcjonalne
                    displayInLayerSwitcher: true                    
                });

I wogóle nie wyświetla markerów, nawet tego domyślnego. Consola bez błędów
