How to run code after each other?

Question

Hi there, a little question.
I call a function that returns the path of a new saved image as a string.
In that function I  use a loader to load the image. After the image is loaded I set the url of the saved image and return it.
Next = id of the new saved image
Imageurl = the url of the image to load.
thumborfull = an indication to see if the thumb needs to be saved or the full image, so the thumb can be saved in a different folder than the full image.
My problem: when I call this function.. the return goes first, and then the loader complete. In the loader complete I set the new path of the image which i want to return.
So, my code runs synchronal, and not synchronic.. How do you get it to run synchronic?
Please some help.
code:
     public var myimageurl:String;
     public function saveImageFromInternet(next:Number, imageurl:String, thumborfull:String):String
          var imgClass:Class;
          //the second way
          var loader:Loader;
          //source code of the second way
          loader = new Loader();
          //notice: NOT _loader.addEventListener,is  _loader.contentLoaderInfo.addEventListener
          loader.contentLoaderInfo.addEventListener(Event.COMPLETE,function(event:Event):void
                var loader:Loader = Loader(event.target.loader);
                    // width and heigt of selected image
               var originalimgwidth:Number=event.target.width;
               var originalimgheight:Number=event.target.height;
               //put original image into bitmapdata
               var bitmapje:BitmapData;
               bitmapje=new BitmapData(originalimgwidth, originalimgheight, false, 0xFFFFFFFF );
               bitmapje.draw(loader.content,null,null,null,null,true);          
               var newimagefile:File=new File();
               if(thumborfull=="thumb")
                    newimagefile=docsDir.resolvePath("Tmtp/I"+next+".mtp"); //image path
                    myimageurl=newimagefile.nativePath;
               else
                    newimagefile=docsDir.resolvePath("Fmtp/I"+next+".mtp"); //image path
                    myimageurl=newimagefile.nativePath;               
               var stream:FileStream = new FileStream;          // create new filestream
               stream.open(newimagefile, FileMode.WRITE);     // open filestream
               var data:ByteArray = encodeToJpg(bitmapje);     // convert bitmapdata to a jpg bytearry
               stream.writeBytes(data, 0, data.length);     // writing the image
               stream.close();
          loader.load(new URLRequest(encodeURI(imageurl)));
          return myimageurl;

If you are concerned that you are losing the url as it is not available from the complete event, you could use a custom event, which allows you to pass your own data into the custom event. Then in your custom complete event object you will still have the url.
