I've no problem with that - assuming I believed that Adam and Eve were historical people in a garden, which I don't.
It certainly isn't unusual in the Bible for God to interact with people in a manner that is clearly designed to accomodate the needs of the people, nor is it strange to find him doing or saying things which pre-figure later events - and ultimately in Christ I believe He became a man.
Though I think the metaphor of humanity being in the "image of God" is far richer and more powerful than mere physical appearance. I believe it is a description of those things that seperate us from other creatures (though other animals share some of these characteristics which is hardly surprising given that we evolved from earlier creatures like everything else). These include a moral sense of right and wrong that seems to extend beyond mere care for self and relatives, ability to relate to others, creativity, abstract thought etc ...
