Here are 11 things the early chapters of the Bible say about being made in the image of God. they all depend on God being prior, above and qualitatively different. THE primary distinction is that he is Creator and this is his creation in which we are his creatures. we are by God, for God and in the image of God. This fundamental separation is the ground of all Christian understanding of identity, meaning and morality

Twofold variety, a community of love. In his image God created a BINITY, reflecting the Trinity, unlike the teeming animals
Speaking. God speaks, calls, self-discloses. So do they
Rule as vice-regents under God
Creativity / separating / taxonomy. God makes things by kinds and calls them and separates them. He invites Adam to name things, thus doing the kind of things God does, as a child with their parent
Walking with God
Dependency on God rather than autonomy from him. Being God-centred
Work. God works, he gives us work
Innocence
Honour
Beauty
Poetry / speaking exultant words

There are plenty of things that being made in the image of God is not. Theologians like to talk about God’s “incommunicable attributes” - things he does not give to others. We are called to be like him in his holiness but not in his omniscience, for example. Four things that are clear at the start of Genesis that being made in him image does not mean:

Moral equivalence to God or being moral agents independent of him
The right to be arbiters of good and evil
The right to be God. The great twisting of Satan was to take being made in the image of God and use it to tempt to want to grasp godhood
That we are just like the other creatures
