In all of the imaging examples, the actual image is obtained only in the diffusing lens and only if the object is behind the focal plane of the lens. And the image is always upside down.
If the object is between the collecting lens and the focus, then the image is imaginary and direct. A ghost and direct image is always obtained also in a diffusing lens.
