Please read the Article Guidelines as they apply to pictures (it gives you instructions). No, the authors do not have to take all of the pictures. But, you will have to tell me where you got them, so that I can look into it. Thanks for the question. Everyone else: You can now submit your articles! We want to build up a database of articles before we start, so we can keep updating. So the sooner we get a bunch of (maybe 15 or so) articles that we get, the sooner we can officially launch this feature. Thanks.
