Question on Posters - please help :)

Hi, i got a message saying imdb wants Posters as the main image, but some are impossible to do such as for Video games (such as Game Boy)  not game box cover art,  because posters do not exist for some titles. did imdb make these posters for the video games?  ALSO woulent imdb want Japanese images first for Japanese titles such as Pokemon? since they are from Japan?
