ActionScript 3.0 :: Replace Some Code Which Loaded An External Image And Triggered And Function Once Completed With Code That Uses And Embedded Image?

I am trying to replace some code which loaded an external image and triggered and function once completed with code that uses and embedded image. The relevant code looks like this.

Code:

[Embed(source='globe.png')]
public function Globe()
{
var imageLoader:Loader = new Loader();

[code]....

The commented out section is where it used to take the loaded image and apply it to a texturemap.I need to replace the lines of code in the first function with something that calls the second function correctly.

I have tried using function imageLoadComplete (e:Event = null)and calling it with imageLoadComplete(); in the first function but although it compile and runs without error, the program does not work properly. I suspect this is to do with the dispatchEvent(); line which I do not understand.
