I'm not really sure which exactly pictures you need (the infobox images or some others). I'm also not really sure, why you want me to upload it, instead of just upload them yourself. If it's because of some rule that requires permission or something, then feel free to take whatever you want from Basilisk wiki.
Well that's hard, as usually those who can and want to edit, are doing it. If you haven't already, you can try giving encouraging messages to the overall new users to the wiki as they edit, giving them courage to do more and to feel helpful. For the more solid ones, if you want to keep them if they seems to get more inactive, you can try giving them rollback rights or forum moderator rights.
You can also try making some threads in the forum for discussing the manga, anime, fav characters, if they were a hero, what their name and powers would be, etc things. And a forum activity feed on the front page, so more people to notice it. Eventually those who discuss things, may start to help with editing.
