Users can upload any image files that they want, but please make sure you use them right away. Unused Images that are not related in any way to AKB48Group and Nogizaka46 will be deleted if not used within one week of their last activity. Meaning that I'll only wait one week after you "unused" it. If you uploaded the images, but didn't use it, I'll wait one week before deleting it. Licensing (see image attached) is still optional, it's just something I came up with to track my own images. I also delete duplicate images, so make sure that the image you want to add isn't on the wiki yet (see Special:NewFiles). I'm making Image Categories right now (although i'm still at Matsui Rena's list) so that it will be easier to find images of members, singles, albums, etc.
I'm also looking for ways to use the unused but related images.
