Made in the image of God or the Holy Court?

Then God said, "Let us make man in our image, after our likeness." Genesis 1:26a(ESV)

This is something that I have struggled over since my Old Testament class in seminary with Dr. Gordon Harris. In my opinion there are really two views to this passage. First, God is addressing the Holy Court. The word "us" refers to God addressing all those a part of His royal court. Second, God is addressing the Trinity. Here the word "us" refers to the Holy Spirit and Jesus Christ. There may be other options, but these are the only two I have heard.

Let's take them one at a time. If the word "us" refers to the Holy Court then by inference male and female would be created not only in the image of God but also of angels or other beings (like the creatures with eyes all over their body). Now, I'm no Hebrew scholar and the two commentaries I have looked at seem to avoid the issue all together (or maybe they think it is so obvious they don't feel the need to address it), but why would God tell the entire court that he is going to make man in their image? Especially since the next verse says we were created in the image of God. So, even though Gordon Harris may know more about the Old Testament than I do I get a sense that he is wrong.

If the word "us" refers to the Trinity of the Father, Son, and Holy Spirit then the passage would make more sense. We are not only made in the image of the Father, but also the rest of the Trinity. We are not made in the image of everyone in the Holy Court, only God. So, I believe that this is the earliest reference to the Trinity in the scriptures.

Again, I'm not a Hebrew scholar. So disagree with me if I am wrong. What do you think?
