Adding image in infowindow of Google Maps?

Question

I'd like to add a float:left logo next to my address in the infowindow, how can I do that? Here is my code:

<script>
  function initialize() {
    var mapCanvas = document.getElementById('map');
    var mapOptions = {
      center: new google.maps.LatLng(18.5231,-72.2929),
      zoom: 14,
      mapTypeId: google.maps.MapTypeId.ROADMAP,
      styles: 
      [{"featureType":"landscape","stylers":[{"hue":"#FFBB00"},{"saturation":63.400000000000006},{"lightness":37.599999999999994},{"gamma":1}]},{"featureType":"road.highway","stylers":[{"hue":"#FFC200"},{"saturation":-61.8},{"lightness":45.599999999999994},{"gamma":1}]},{"featureType":"road.arterial","stylers":[{"hue":"#FF0300"},{"saturation":-100},{"lightness":51.19999999999999},{"gamma":1}]},{"featureType":"road.local","stylers":[{"hue":"#FF0300"},{"saturation":-100},{"lightness":52},{"gamma":1}]},{"featureType":"water","stylers":[{"hue":"#0078FF"},{"saturation":-13.200000000000003},{"lightness":2.4000000000000057},{"gamma":1}]},{"featureType":"poi","stylers":[{"hue":"#008349"},{"saturation":-1.0989010989011234},{"lightness":11.200000000000017},{"gamma":1}]}]
    }
    var map = new google.maps.Map(mapCanvas, mapOptions)
    marker = new google.maps.Marker({
        map: map, 
        position: new google.maps.LatLng(18.5231,-72.2929),
        icon: "img/mapmarker.png"
        });
    infowindow = new google.maps.InfoWindow({
        content:"<b>Title</b><br/>123 Address<br/> City,Country" });
        google.maps.event.addListener(marker, "click", function(){infowindow.open(map,marker);});infowindow.open(map,marker);
  }
    google.maps.event.addDomListener(window, 'load', initialize);
</script>

Simplest way. Add a div float:left in the infowindow.

infowindow = new google.maps.InfoWindow({
    content: "<div style='float:left'><img src='http://i.stack.imgur.com/g672i.png'></div><div style='float:right; padding: 10px;'><b>Title</b><br/>123 Address<br/> City,Country</div>"
});
