I'm not sure what you're asking here, so I'll give the answers to what I think you might be asking. All the images will still be displayed in-game in their appropriate places; the process I mentioned above is to get at the images by themselves, without having to go to the appropriate scene in-game. The existence of an "image-pack version" was a Flash-only thing; all it was, was having images in-line with the text in certain scenes, and for some reason the devs decided to roll that into the base experience when they ported TiTS to JavaScript.
