Only if you are talking about God's physical image -- and anyone looking around can see that would be a false assumption.
Physical or not doesn't enter into it. If I do an image of man as a likeness on canvas, it is no less an image if it is rendered in 2d rather than 3d - it is still a representation or likeness. Given that Scripture then says that the animals were made first, and then God made man.. then it elaborates that God made man out of the dust of the earth.. You're reaching. No assumptions needed.
