Images should not have borders around the artwork. Crop them out when required.
Pornographic works should have appropriate censoring of the genitals and visible breasts.
Local image upload is currently available to moderators only.
For anime, the cover can be a key visual, announcement piece for a new anime, a textless VHS/DVD/BD cover, official illustration, and, in cases where nothing decent is available, a screenshot or cropped piece from the work itself.
For manga and light novels, where possible, the cover image must be the Volume 1 release of the original print run for the series.
For series that are web-only or have yet to receive a printed volume or eBook, the cover can be announcement pieces or official illustrations.
If nothing else is available, the first page of the series itself will do (many one-shots will have this).
Please don't crop volume covers for written media unless removing spines or borders. It is fine to upload them directly.
