I hate every picture my friend posts
Is there something wrong with your friend's photos?
Yeah, they have her face in them.
If you don't like your friend's posts then you don't need to look at them. You should just mute their posts and move on.
I told her to stop posting but she doesn't listen.
It's not kind to try to control other people's social media postings. It's best if you just ignore her social media if you can't stand to look. Or even try to politely look and then not give it another thought.
