What does it mean when a guy likes your pictures on Facebook?

I recently hung out with this guy and it was also our first time actually meeting each other. Since we've hung out he's talked to me on Facebook and also liked my profile picture, which is just a pic of me. Is he trying to let me know he's interested?

Yes, I've done it myself. Didn't work though

yea if i did that to a girl it would most likely mean that i like that girl. also if he just met you and already did like your photo that means hes probably intrested
