From what I've been able to gather, the images that lead to each show/movie are the most updated poster for the show. Shouldn't Jessica Jones use File:Jessica Jones Season 2 NYCC Poster.jpg and Inhumans use File:Inhumans Poster.jpg, which are their most recent posters? I would fix it myself, but the page is locked.
I actually posted this on the talk page for the Main Page, but I never actually got a response.
