There is an option "Automatic resize/recompress picture if needed" that you probably unchecked.
I see you could post pictures in the comments and that some pictures on https://www.imcdb.org/movie.php?id=318913 are waiting to be validated by an admin but I doubt they would be acceptable.
If things disappear, it is usually meaning that they were not acceptable.
From what other admins said, there were already things that were rejected for that one. So at some point you should stop trying...
Same for re-creating accounts each time: you were banned for bad behavior and useless contents.
