Need a tip for an image viewer

Question

Hi guys i'm trying to make an Image Viewer app and i couldn't find a way to tell my main AS3 class which is the Image that opened the application.
I already specified images in windows to "Open with" my Image Viewer, and indeed my application executes but, is there a way to register the path of the file that opened my application?
So far i've only seen drag&drop implementations, and i imagine that your answer will be a negative but i'm trying to find a solution to this because it's the only problem that keeps me from replacing the Windows Picture and Fax Viewer, so any tip, any idea, will be appreciated.

Thanks mate!
It is now possible to do it with AIR 1.5.1
In case someone needs it, here's the code that does the magic (AS3.0)
import flash.display.NativeWindow;
import flash.desktop.NativeApplication;
import flash.events.InvokeEvent;
var fileLoader:Loader = new Loader();
addChild(fileLoader);
NativeApplication.nativeApplication.addEventListener(InvokeEvent.INVOKE, handleInitializationArgs);
function handleInitializationArgs(event:InvokeEvent):void
    // get the application arguments from
    // the InvokeEvent object
   var args:Array = event.arguments as Array;
    // if arguments were provided to the application
    if (args.length)
        // of the arguments provided, assume the first
        // is of the associated file type
        var fileToOpen:String = String(args[0]);
        // load that argument as a url into the loader
        fileLoader.load(new URLRequest(fileToOpen));
