DO NOT UPLOAD FANART. Fan-drawn images, fan colorings, and other images that have been edited (other than for simple resizing or cropping), will all be deleted unconditionally.
Uploading leak images is not allowed.
Images from the visual novel and anime is allowed.
Websites such as deviantART, Zerochan, ect... that lets users upload fanart shall not be used on the wiki. You are stealing other peoples work and using that image without the artist's permission.
Please don't upload .gif images, not even in you convert a .gif into another file format before uploading. The .gif format does not handle quality properly. It has a limited color depth, and as a result the moment you save an image with the .gif format it loses a large amount of quality.
