On Cover images (not textless covers, or anything else), we use "none" because we don't want cover images appearing in character image categories - which is where they would go if you filled out the subject field with a character name. For any textless cover or comic single panel, the character name is preferred. Leaving it blank adds it to Image Subject Needed.

So, for Cover images, "None" is preferable.

The Next/Previous fields don't fill in automatically, but they're optional fields, and nothing bad happens if you don't fill them out. The proper format for filling that out is "filename.jpg" It will automatically convert that to a link to the previous or next cover.
