import mx.core.BitmapAsset;
[Embed("assets/Fair.png")]
const Fair:Class;
[Embed("assets/Cldy.png")]
const Cldy:Class;
[Embed("assets/Sunny.png")]
const Sunny:Class;
[Embed("assets/Fog.png")]
const Fog:Class;

var desc:String = new String();

if(desc == "Fair"){
var FairImg:BitmapAsset = new Fair();
TemperatureImageId.addChild(FairImg); //TemperatureImageId is the Id of graphic symbol
} else if(desc == "Cloudy"){
var Cloudy:BitmapAsset = new Cldy();
TemperatureImageId.addChild(Cloudy);
}else if(desc == "Sunny"){
var Sunny:BitmapAsset = new sunny();
TemperatureImageId.addChild(Sunny);
