Looking through the CoS adventure in the compendium, and there are several images not included that are in the actual book: specifically, the ones in the Monsters and NPC Appendix. Pictures of Ezmerelda, Izek, Pidlwick II, Rictavio, and Vladimir are all missing.
Also, I think a collection of all the images of a book in one place would be very useful.

I can confirm that most of the images from Curse of Strahd are missing.
