This is something that you will be dealing with annually - its clearly something that's important to your MIL. It also sounds as though while she wants to maintain civil relations with you, she's also having a some difficulty navigating what is appropriate and finding a balance. I think a lot of the In-Laws in these situations struggle - there's not a lot of advice out there for how they should behave.
Do you think she left your pictures out of the book to deliberately hurt you? It doesn't sound like you do, instead it sounds like maybe she was either a little thoughtless or more concerned with her son's feelings. It's probably better to attribute the kindest motivation to her. I know this kind of thing hurts a lot, but I think you just have to be the bigger person here. Go ahead and send some photos (and definitely include a reasonable amount with you in them)- but I wouldn't say anything to her.
If you don't like the end result - I would just make your own book entitled "Mommy and Me 2014", all about your adventures together with D this year. I bet she'd love it!
