// Embed the image once and refer to the Class [Bindable] [Embed(source="../assets/images/myImageFile.png")] public var myImage:Class; This is helpful if you're using the same image in several places, this way you only have to embed it once, and if you change the image file name you only have to change it in one place. You can also create a Class that holds all the images and you can get an instance of that Class to refer to your images. For example: package com.view {  import mx.binding.utils.BindingUtils;  [Bindable]  public class AssetImporter  {   private static var instance : AssetImporter;   //return singleton instance of AssetImporter   public static function getInstance() : AssetImporter  &nbsp{    if (instance == null)    instance = new AssetImporter();    return instance;   }   //put your images here   //One   [Embed(source="/assets/imag...

Sweet eh? <mx:AdvancedDataGrid  id="mainADG"  width="100%" height="100%"   dataTipFunction="testTip" > [...]  <mx:AdvancedDataGridColumn   dataField="Name"   headerText="Name"   itemRenderer...
