If you make an account on the Global Link, you can sync your X/Y game with it, and then when you take a photo in the game at one of the photo spots (such as in front of Parfum Palace or the Battle Chateau for example), you have it uploaded to your account via Game Sync. And then you can take the link from that and use it to post the screenshot here.
I would put a screenshot of her, but I sadly don't know how to take one on my 3DS...
