How to upload BitmapData in flex 4 to server with preloader?

Question

Hy,

Im creating a upload component that do these things:

• select multiple images
• convert to BitmapData
• resize if is too large
• create a thumb(itemRenderer) and add it to a list

And the problem is how to upload them with a preloader for each image when a button is pressed. Anybody know how to do it?
