How to preload external jpg

1

Hy all

I’m using the following code to load a background image into a container movie.

 
on (release) {
 this._parent.background.container.loadMovie("fundo02.jpg");
}

Now I would like to add a simple preload sequence to the action. So that after klicking the button a "loading"clip apears until the Image is all loaded.

Then I’d like the new image to smooth in over the old image instead of suddenly appearing. Is that asking to much?

Thanks in advance.
