The image, from Venice, Italy, shows off Spider-Man in the regular costume on a boat with Samuel L. Jackson (or a stunt double).
Regarding how Nick Fury fits into things is unknown, but following The Avengers 4, maybe Fury is "active" again and helps out Spidey around the world facing whatever threats loom large.
Samuel L. Jackson will also be returning for Captain Marvel.
