Answer

impression is a quick study that may be missing detail and facts.  For a better understanding, more study would be needed.

Image is the two dimensional depiction or representation of something often taken by a camera- but may be made with some other means.

Answer

I think maybe the subtle difference between the 2 words is as the follows:
If you have an image of something or someone, you have a picture or idea of them in your mind. 
Your impression of a person or thing is what you think they are like, usually after having seen or heard them.
