Image loaded successfully, but fail to draw bitmap of it

Question

I  have a image loaded from  different domain. The checkpolicy is set to  true and crossdomain file  has no problem.  The image isn't that large,  2,304px × 1,260px
In the application, I will draw the bitmap image with this call
new Bitmap(Bitmap(imgLoader.content).bitmapData, "auto", true);
The   weird part is, there is 1% chance... the application can't draw the   bitmap... it will just be empty. It never happens to me, but some of my   users are complaining they can't see any image. I think they have  pretty  decent computer, and see the application on ie8 or ff4
Not   sure is there anything I am doing wrong... I am sure the image is   loaded to user's browser, but the application just can't draw it....
Can anyone help?
Thanks a lot

I have the crossdomain file hosted on the site... and i have the code like this in my app
ImgLoader = new Loader();
context = new LoaderContext();
context.checkPolicyFile = true;
ImgLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onImgLoadedHandler);
ImgLoader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, onImgLoadedErrorHandler);
ImgLoader.load(new URLRequest(Params.imgURL), context);
private function onImgLoadedHandler(e:Event):void
     ImgLoader.contentLoaderInfo.removeEventListener(Event.COMPLETE, onImgLoadedHandler);
     ImgLoader.contentLoaderInfo.removeEventListener(IOErrorEvent.IO_ERROR, onImgLoadedErrorHandler);
     imgBmp = new Bitmap(Bitmap(ImgLoader.content).bitmapData, "auto", true);
The thing need to mention is my ImgLoader is a public variable in one class... because I need to create another copy of that image in a different place... so in that clasee, I will reference the ImgLoader variable and create a another bimap with code like
imgBmp2 = new Bitmap(Bitmap(ClassName.ImgLoader.content).bitmapData, "auto", true);
