image remove

Hello, I am writing from the production company of the film Akıldan Kalbe. Someone we don't know has upload a few images, and I would like to delete them. I am unable to do so. I want only the poster to be set as the main image. Even though it shows correctly when switching to the pro version, there is another image when I open the page. Could you please help me and remove the character posters besides the main poster?
