Is God an Exalted Man?

“And God said, Let us make man in our image, after our likeness.” —Genesis 1:26

“God himself was once as we are now, and is an exalted man… I say, if you were to see him today, you would see him like a man in form—like yourselves in all the person, image, and very form as a man.” —Teachings of the Prophet Joseph Smith, p. 345

When God said “Let US make man in OUR image,” to Whom was He referring to? To Jesus or the Holy Ghost?

“By obedience and devotion to the truth he [Jesus] attained that pinnacle of intelligence which ranked him as a God, as the Lord Omnipotent, while yet in his pre-existent state.” —Bruce R. McConkie, Mormon Doctrine, p. 129

“The Father has a body of flesh and bones… but the Holy Ghost has not a body of flesh and bones, but is a personage of Spirit.” —D&C 130:22

Since Jesus was God BEFORE He obtained a human body, and since the Holy Ghost is God, yet has no physical body, how can God’s “image” be human?
