New Q for preloader and scrollwindow


I done tutorial for preloader from and works OK.
But I need preloader like on this location

I was trying over and over with this tutorial but instead of rectangle I used pictures: one with white contour, second black, and finaly real picture. It works in Library but not as loader.

Just for notice rectangular preloader works, but not with picture.
I do Trace bitmap, and without but things ar the same.

Where am I wrong?

Also, I need help for scrolling pictures on the same location.

What is AS for rollOver like that?
