How do we change our main / official poster on TMDB?
Hi! A film I worked on has a new poster and we're wondering how we can update / make the new poster (currently the third poster in the poster tab of our page) the main one?
A viewer of the film uploaded / created the page and we are unsure on how to make the official film poster the main one on TMDB.
Here's our short film page: https://www.themoviedb.org/movie/803882-fruity
Any help will be much appreciated! Thanks so much :)

Images take position depending on votes.
1 vote per user per image.
Most voted is the main one.
Setting the image language also helps.

I suggest you go in there and vote.
That should solve the problem.
