Is it bad that my boyfriend likes my friends pics on social media?

My boyfriend doesn't know my friend. Never met her. He likes lots of people's pictures on social media, he's not stingy with likes. But I don't trust my friend because she's told me she's jealous of me before and she said my boyfriend is cute before when she saw a picture of him. My boyfriend likes her pictures though, all the pictures except the one where she's with her boyfriend. He likes everyone's pictures though. Is that embarrassing? Is this a cause for concern or should I just let it go?
