Fractals are a different kind of image.
They are born in mathematical equations and then begin a life of their own in an infinite universe very different from ours. We can find fractals in nature. If you look at a tree from a distance, you can see its overall shape. As you come nearer, you can start to see the branches and, if you walk a little closer you can see the leaves. If you were to walk towards a square, you wouldn't see such detail.
