See notes for the images.
Self explanatory, there's some poster images on here that I feel could be doing with changing. Letterboxd is synced up to Themoviedb in which the highest rated poster image will show up on LB. It doesn't always work like that for some reason though.
If the poster image showed on LB isn't the original poster art, then it's a likely candidate. However, it can also include alternate art that I personally like better. Feel free to suggest away.
