Actually, the English word "image" simply means a representation of a person or thing ... including such truly 3-D representations as a statue or bust. What you have been saying about "image" applies to the word "picture" -- which is by definition flat or 2-D -- but not the word "image." Etymology bears this out. "Image" comes from the Latin
imago, which was often used by the Romans to refer to statues or busts; whereas "picture" comes from the Latin
pictura which originally meant "a painting." So there is nothing contradictory about the term "3-D image," but, technically, it would have to refer to a statue or something like that. As you and others have already pointed out, though, people tend to use that term somewhat inaccurately to refer to a picture that gives the illusion of being 3-D.
