If by together, you mean simultaneously, then the conditions for Eve's creation would be the same as that of Adam, and specifically, she would also have been created in God's image directly, rather than by proxy.
Show me one single passage from the Bible where the phrase in God's/his image is used in direct relation to Eve's creation.
Uh, OK, I'll play: "So God created4 man in his [own] image, in the image of God created1 he him; male and female created1 he them."
By the way, remember that this was not done in English. You might also want to look at the original Hebrew for a further understanding of the meaning.
Just to make sure I understood you - are you suggesting that women are not created in God's image? Just men are?
If I misunderstood, I apologize immediately.
