What does it mean when a girl likes a picture you post on instagram within a minute?

Anonymous
So I like this girl, and I think she likes me too, but we never talk. I added her on instagram about a week ago, and decided to post a picture up to see how fast she would like it. Within a minute (actually it was directly after, like 5 secs) she liked it, So I liked one of the pictures she posted the same day. What do you guys think about this?
She likes you.
Probably just a meaningless like.
She probably liked your pic hoping you'd give a like on hers.
