I need to vent. MIL Drama.

I need your unbiased opinions. My husband and I went to his parents home for a thanksgiving dinner tonight. We hadn’t been over for quite a while. ( we’re not very close) As I come in I see not one, but two photos of us blown up and framed on their living room desk. I never gave them those....my husband doesn’t even have them. They were a random selfie I posted on my instagram a while back. They went through my account copied and printed the photos without our knowledge. And while I get the intention was sweet. It’s weird, and inappropriate. Am I right? My husband doesn’t think I have a right to be mad. Because I posted online for anyone, therefore they had a right to it. I still feel it violated me and crossed a boundary that wasn’t ok. What do you think?
