What does she want exactly?

There's this girl, we knew each other through internet and it seems like we have a crush on each other. We speak daily. Anyway, I've returned hometown and we'll meet in two days or something for the first time. Today I've seen her posting a random shots on Facebook of her and a male friend (laughing, exclaiming, depressed, etc .. ) The picture was taken like 6 months ago which is weird especially it's the first time to post pictures that kind. Is that a thing? Does she want me to feel jealous and tell her that I love her?
