It's because you're not passing an Icon to the marker options, just an URL (which the API supports but then it will only return you a string)

you should create a Icon with the size attribute (else the size property will stay undefined), something like this will work:

var myIcon = {
        url: "icon.jpg",
        size: new google.maps.Size(10,10)
    };
var marker_ new google.maps.Marker({position: Latlng, icon: myIcon});
