How to change height and width of images loaded into movieclips?

1

Hi,

I’ve loaded images dynamically into movieclips using .loadMovie();

I need to adjust the height and width of the images after they are loaded, does anyone know the syntax for this?

The images being loaded are 40x40px in dimension, but I want them to display at 20x20px.

I thought I could just do this, but no dice:
menuitem.mc_menuimage._height = 20;
menuitem.mc_menuimage._width = 20;
