Movie Posters Not Matching Images On File

Hi Guys.

Ive just upgraded via a fresh install from 15.2 to 17.1 and am running the Aeon MQ7 skin.

When I add my new sources I selected Local Information only as I use MediaElch to manage my movies.

The strange thing is that some of the movie posters (dvd covers) are animated GIFs and as much as i love it I cant figure out where they are coming from.

If I have Local Information set should that stop and scrapers from scraping from an external source?

How can I stpo Kodi scraping if I already have Local Information already set?

Thanks.
