Cannot addChild on stage after EventDispatcher successfully loaded the image?

[FONT=Calibri][SIZE=3]I am trying to learn how to use EventDispatcher. I create xml gallery where I am loading content via xml. In this particular case, I am not loading a sequence of multiple images. I load just one image. I traced the path to the image location and it is correct. I have a very hard time placing the loaded item to stage. I can trace EventDispatcher functions from EventDispather Class. When I do that, the trace statements confirm that the image is loaded. I am wondering what I should do in order to place the image on stage. I definitely cannot do it from EventDispatcher class directly or I am missing something. Below is my EventDispatcher class.[/SIZE][/FONT]

[FONT=Calibri][SIZE=3]Please help me to find out about the correct technique to add the loaded item on stage after EventDispatcher was run. Below is the class of my EventDispatcher. [/SIZE][/FONT]

[FONT=Calibri][SIZE=3]Any advice is highly appreciated. Any good tutorial link is also a great help for me. Thank you in advance.[/SIZE][/FONT]
