I doubt you would do very well if all you want to protray is
what "hip today".
You mentioned that you would need images that depict the youths'
halcylon days, then may I suggest you brainstorm and think
deeper!
What exactly is the cause of teenage halcylon and hedonic?
Ignorance, rebellious nature and all - just my two cents worth. For
I feel that most of your school mates would be coming from the
"hip" perspective, so you might as well make the best out of it and
present something different and deep.
Edit: I'd encourage you to go all out and take some shots of your
own, instead of collecting images over the internet.
