In Flash Builder (flex 4) I try to use next code to set selected by user (from file system) Image as a repeated background. It worked with mx:Image but I want to use cool repited capabiletis of s:BitmapFill.

BTW: Technic I use also does not work with S:BitmapImage. Also FP does not return any errors. What Shall I do with my code to make it work?

            arr.push(new FileFilter("Images", ".gif;*.jpeg;*.jpg;*.png"));

            img.source = fileReference.data;
            Alert.show(ObjectUtil.toString(fileReference));

           }

  <s:Rect id="backgroundRect" left="0" right="0" top="0" bottom="0">
     <s:fill>
        <s:BitmapFill id="img" source ="@Embed('1.jpg')" fillMode="repeat" />
     </s:fill>
  </s:Rect>
        <mx:Button id="btn"
                  label="Browse and preview..."
                  click="btn_click(event);" />

Any ideas?
