What do you do when your MIL gives you a picture to put in your baby's nursery, not just any picture either...?

She told me over text that she made the cutest picture frame for the baby's room, which has a baby pic of, that says "my mom" a pic of daddy as a baby "my daddy" a pic of baby "me" a pic of her as a baby "my grandma". How am I supposed to hand this up in my beautiful nursery, which has no room left for anything! Also, I see his nursery more as MY room right now! I have pics of him, that make me smile from when he was just born (he's 4 months) and my rocking chair that I enjoy rocking him in. He sleeps in my room still, since he's nursing once during the night, and I use this nursery for clothing changes, diaper changes, and daytime nursing. The room brings me joy. It will be more for what my son likes, when he is a little older. How can I hang this photo of us as babies, with her in it also? I find it weird :(
