Best way to get metadata that actually appears when running Kodi?

Hi,

I am using Kodi 18.9 for my personal Movie collection. When I run it sometimes the media images appear and sometimes they don't?

I have been using Media Center Mater to scrape for metadata which includes the images displayed for each movie and TV Show.

But even if there seems to be the necessary images in the movie folders they don't always get displayed in Kodi?

Someone on YouTube is recommending Tiny Media Manager. I am just starting to try this option. Not sure what it does yet.

Does anyone here know a best way to get the media images to coordinate with Kodi so that they display when running Kodi?

Is there a best plugin for Kodi to get this done?

Thanks,

John
