The top poster should be a "clean" poster when one is available. We count on you guys to up-vote the best textless posters in each languages to the top. While this policy might not please everyone, it is simply a matter of consistency in our design.
Moderators can set a poster as primary when needed, for example when the top-voted poster is not title-only, has an imperfect aspect ratio or when a better poster is uploaded. The guidelines for primary posters requests are located here.
