Am I over reacting?

Ma

Okay so my boyfriends aunt took pictures at Easter of me my boyfriend my daughter okay whatever I was scrolling through Facebook and seen my boyfriends step mom so out of curiosity I go on her profile and see she's tagged in photos of MY daughter that his aunt posted so I click on it and go onto his aunts profile and she has all kinds of pictures posted of MY daughter from Easter!! I just now found out about it I'm frustrated because she didn't ask me if she could post them it's my daughter she could of atleast tagged me but nope she made sure to tag everyone else in the family though! My boyfriend doesn't see it as a big deal how would you feel?
