oh, perhaps I didn't explain myself well.
Say I'm importing an image of a person standing in full figure against
a white background. When this image is in front of another larger
image, you can see the white background behind the person. I just want
to make the white background behind the person invisible so it just
looks like the person is standing in front of the other picture.
