Hmm... Well I guess it really wasn't too clear, but Fly got it. Ok, let me go into more detail here.

Take any picture that would go well with continuing the story... Kind of like the Choose your own adventure books you read as a kid, except someone else is choosing it for you.

Example-
I went out to grab a bite to eat last night
I didn't feel quite right, as if someone kicked me in the stomach
So I ran to the toilet, but it was occupied
And so on.
