    Can someone tell me the correct way to blend two images together so that I am taking a background image and putting it behind the girl sprite?

    The problem I am having is that the size of the background is not what I want it to be.

    The 2nd image I attached is of the sprite editor and it shows that there is a lot more transparency and I want all of the transparency to be black.

    Use 
    lerp(background, image, image.alpha)

    This is what Blend with Override mode should do.

    Thanks, I used lerp and that helped!
    Also I found out why the sprite was cut.
    I needed to change the Mesh Type from Tight to Full Rect.
