(Colossians 1:15) He is the image of the invisible God, the firstborn of all creation;
Well, if God is invisible then he cannot have an image, including even one created by means of a mental construct. However the assertion that he is invisible seems not to be true because you apparently can see, him but at the price of losing your own life, which in anyway you will end by loosing one day or another due to the fact of Adam having decided to eat an apple instead of a pear. . Morality of the story. You can see the invisible God but what you cannot do is to tell others how he looks like.
King James Bible
"And he said, Thou canst not see my face: for there shall no man see me, and live"
