Flex: Actionscript project swf is not working after export the release build...

Question

Hi guys..
   I tried to built a project with AS3 only in Flex. When I run the project in flex, everything looks fine, but when I export the release build, the images that are supposed to be added are gone. I appreciate if someone can help me about it.
          init();
            public function init(loadedVideoCount:Number):void{
            singleHolder=new singleVideoCont();
            singleHolder.x=loadedVideoCount*singleHolder.width+2;
            singleHolder.y=6;
            singleHolder.buttonMode=true;
            addChild(singleHolder);
            this.addEventListener(MouseEvent.CLICK,onClick);
            showTn();
        private function showTn():void{
                imgLoader = new Loader();
                imgLoader.load(new URLRequest(_tnPath));
                        imgLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS,onProgress);
    imgLoader.contentLoaderInfo.addEventListener(Event.COMPLETE,onImgLoaded);
        private function onImgLoaded(event:Event):void {
        singleHolder.progBar.alpha = 0;
               var image:Bitmap = imgLoader.contentLoaderInfo.content as Bitmap;
                image.width=TN_WIDTH;
                image.height=TN_HEIGHT;
                image.x=3;
                image.y=3;
                singleHolder.addChild(image); //this line work when I run the project inside flex but the images are gone when I test my release build...
                imgLoader.contentLoaderInfo.removeEventListener(ProgressEvent.PROGRESS,onProgress);
                imgLoader.contentLoaderInfo.removeEventListener(Event.COMPLETE,onImgLoaded);
                //imgLoader = null;

The link you provided is to the SWF file, not to an HTML
file, so no one can test your HTML file.
Have you checked the code for the embedding of the SWF file
in your HTML file? I don't use Dreamweaver much, but I do know that
if you start assembling a Dreamweaver file without first saving the
HTML, embedded graphics and other items are inserted as direct
links to the files on your computer, rather than as relative paths.
There is one other possible issue: I note that your swf is
called CWABanner.swf. Depending on your FTP settings, it is
possible that your server is forcing all file names to lower case
(a common practice). Which means the file on your server will be
cwabanner.swf. Again, depending on how the web server is set up, if
it is case sensitive, it will treat CWABanner and cwabanner as
separate files. So if the HTML calls CWABanner.swf, but the FTP
upload has forced a rename to lower case to cwabanner.swf, the HTML
file will not find it. Check this out, or to be absolutely certain,
rename everything to lower case: the file name itself and the
reference in the HTML file.
