Unable to delete duplicated and poor quality photos

Hi,

I noticed yesterday that part of the photos displayed on IMDb for the movie « Cadejo Blanco » were of poor quality:

https://m.imdb.com/title/tt15385142

That is why, I added 14 photos of better quality. All of these additions were accepted by IMDb. Please find some of my contributions here after:

But when I asked to delete old photos that were duplicated or with a lower quality, all of my contributions were refused by IMDb.

Please find here after the refused contributions I made for real duplications:

I also made contributions for poor quality photos that were blurred, of no real interest or too dark. But all of these contributions were declined also:

Etc.

Can you please at least delete the duplicated photos listed here above?

Can you also please have a look to the 50 other photos previously added (I find that some of them are of poor quality), in order to only keep for this movie good quality photos?

Thanks for your help

Best regards
