Mutliple Masks applied to one Image...HOW?

??? How do you do it?

I know how to have just a sing mask, work for a single image. But i’m looking to animate the masks, to reveal the image, by doing so i need to use 2-3 layers of masks to animate them. How can i get all 3 layers masks to apply to the underlying image? I can only get one to work for it, the other 2 just do nothing.

Thanks for any help you can give. :pope:
