It also has a physical component. For one, because God had to become flesh in order to redeem us - he didn't just snap with His fingers and we were gucci. See the first part again:
1701 "Christ, . . . in the very revelation of the mystery of the Father and of his love, makes man fully manifest to himself and brings to light his exalted vocation."2 It is in Christ, "the image of the invisible God,"3 that man has been created "in the image and likeness" of the Creator. It is in Christ, Redeemer and Savior, that the divine image, disfigured in man by the first sin, has been restored to its original beauty and ennobled by the grace of God.4
But you must not intertwine that with "nature" (before the fall). God made us - and in a mysterious way, and although God is not material so to speak He still put the effort into us to form us as we are. We somehow are to a certain extend also a physical image of God - but of course in a very abstract way because of what I said above.
One thing I recommend you not doing either is to try to fathom the word "concept" in the way we as humans would use it. God's conception of us is so much more than "just a principle" - so much more than we are able to fully grasp.
