the existing primary was provided by a random partner

https://www.imdb.com/title/tt6586344/mediaindex?refine=poster&ref_=tt_mv_close

this entry right now has some random screenshot as a primary instead of a poster

does "partner" include robot stores like amazon? does any image provided by a partner take priority even if in the wrong categoy?

like a "partner" comes sees that poster is ok and just uploads a publicity photo. will it take priority over a poster uploaded by a contributor?
