Adding data to a Tv Show

Hi. I’ve been the only one who edited and made an imdb page for a tv series in my country, i messaged the production to deal with it and I got no response, I think they’re not interested yet. My problem is that I’ve been adding some official trailers, videos and pictures and they’re not adding to the page and somehow I got capped at 20 pictures, i can’t add videos or trailers, and the pictures are old, from other seasons, and I have to add a few from the newer one. Is there anything I can do to add any new content like pictures etc?
