Just curious - can you name any others which are image-based in the
same way as Smalltalk/Squeak?

How about Common LISP (with CLOS) and FORTH for two? FORTH isn't OOP, but at least one author described how an OOP FORTH could be done (Dick Pountain). FORTH doesn't save "images" as much as they utilize the source code model: start up with the core, and load extensions from source. Other than that, the model is the same.
