Some/many Common Lisp implementations. But there are a bunch of Common Lisp implementations which are not image-based. Another difference might be that most image-based Common Lisp implementations don't use portable byte-code. Some are using byte-code engines, but those are usually not portable across operating systems and/or machine architectures.
