For that one, it mostly means that it needs to have the appropriate categories. Licensing patterns for all images are covered in the image upload window:

"Fanart must be licensed to its originating artist, and must have the "Fan Images" category applied to the image. All fan art must also be used on a fan article, and not simply to decorate your user page. Uncredited, uncategorized, or unused fanart will be deleted, and may be locked to prevent reuploading."
