Girl sends me a snap of condoms, how should I take this?

So this girl and I have been talking lately and we both have shown sign interest in each other. The other day we were snap chatting each other and she sent me a photo of her friends bag with a couple condoms in it and some random caption. Should I take this as a sign, or how should I take this? Flirting?
