Error loading local image

programming flash

I am try to load a local image, but are constantly getting :

Error #2044: Unhandled IOErrorEvent:. text=Error #2035: URL Not Found.

although i am 100% sure the path is correct, infact there is no path, image is in current directory. I am using the following code:

var pictLdr:Loader = new Loader();
var pictURL:String = "background.jpg";
var pictURLReq:URLRequest = new URLRequest(pictURL);
pictLdr.load(pictURLReq);
this.addChild(pictLdr);

Does anyone know what could be the problem?

thanks
