How to upload Art and update Cover?

[ishtarclover]

There is an old manga with incorrect cover. I found a better one and I would like to update it but I couldn't find any button to do that. Does the site no longer support that feature?

I couldn't share the manga title because it is a pornography manga.

Send in a report on the manga and provide the details and a link to the image (imgur, gdrive, etc)
