I'm not completely positive I understand what you are trying to do. Are you trying to just use one image to mask the other?

One thing I am seeing is that sprMaskedImage is not added to the display list. try doing addChild(sprMaskedImage);

I have two images and i want to mask the one with the other. So i instantiate the images from the library and put each to a sprite. Then i set the mask property of the first image to the second sprite and i add it to the display list. But when i test it does not work, i mean the mask does not appears on the screen.
