Colleague sent me picture about the random things he was doing, does it mean he thinks about me or likes me?

I like this colleague, but never had a chance to talk too much to him. We sometimes chat a bit online but always about work. One day I was thinking about him again because I like him, I didn’t know if I should send him a message about my private life this time instead of work related topics. Then all of a sudden I received a message from him with a picture what he was doing right now. Does it mean that he likes me as well?
