What does it mean when a girl sends you random pics on snap with no captions?

So, i met a girl on an app (Wink or somethin) where you can find more friends on Snapchat. Right after we added each other, she hmu first by sending me a random pic (either a pic of her room or a half selfie pic) with no caption. I tried starting a convo but she always end up Snappin me back a random pic with no captions. Idek even know what to do so i did the same and we have a streak rn. Any idea what it means tho?
