Guy asked me my pictures?

I am talking to a guy who works in the same office as mine. We see each other but never had a talk or met each other personally. One day, he resigned from office and it's been a few days since we have been talking to each other. Suddenly he is asking me for my pictures. It's not that he has not seen me or that I have not posted any pictures on Instagram. Why is he asking for my pictures? Should i continue talking to him?
