retrieve marker icon from marker data set

I'm making a website using Google Maps API v3. Markers are added into the map with attributes being taken from marker data

Marker Data set

var markerData = [ "lat": '21.0236081', "long": '105.789596', "icon": 'http://i.imgur.com/0Js6A7w.gif', "description": 'blah blah'
];

Pin marker onto map

for (var i = 0; i < markerData.length; i++) { var data = markerData[i]; var myLatLng = new google.maps.LatLng(data.lat, data.long); var image = "'" + data.icon + "'"; var marker = new google.maps.Marker({ position: myLatLng, icon: image }); (function (marker, data) { google.maps.event.addListener(marker, "click", function (e) { infoWindow.setContent(data.description); infoWindow.open(map, marker); }); })(marker, data); markerList.push(marker);
}

I couldn't get the link to put into 'icon' attributes of my markers. Can someone give me some advice?

Thank you all!!
