change .nfo file

[DZDZzzZ]

I created .nfo file through scrapping in Jellyfin. And I found the image path in the .nfo file is too complex to organize image. So I tried to changed the image path to a new path in nfo file. When I refreshed the metadate through scan for new and updated files, the poster and actor images will not be displayed in Jellyfin. And if I tried to use other methods to refresh the metadate, in .nfo file, path of art would disappear, like </ actor>,and the path of actor would become the previous path. 
So is there any way to display a picture of my new path?
Thanks.

A lot of what NFOs do is for Kodi and not for Jellyfin. The image paths is one of those things that only matters to Kodi. Images must be named and located where Jellyfin wants them to be. The image path provided in the NFO is not used for Jellyfin clients.

So how can I know which location and what name Jellyfin wants? For example, if I have a video without a poster and an image I want use it, thus how I can do to store the image location information in the nfo file, which can prevent images from disappearing when refreshing metadata.
Thanks.

When you enable saving of image with your media in your library settings in Jellyfin, it will automatically save the images where they need to be.

Once Jellyfin has laid down the initial images and metadata you can customize. Either by replacing the images in the file system or using the Jellyfin UI.

Tiny Media Manager is an external tool that can also automate this process.

We have documentation providing example naming and relative locations for the images if you want to do this manually.

It is the pervious poster path: 'D:\Data\Jellyfin\metadata\library\b9\b9c533a88fa6e293e4b735bbbf748e6d\poster.jpg'. The folder name seems to be a hash value, or something, rather than a movie name. So I try to modify it to a movie name, like "'D:\Data\Jellyfin\metadata\library\movie\poster.jpg". But it does not work.
Moverover, if I select the movie folder as the folder to store the poster in previous library, which method should I choose as refreshing metadata to move images into new folder?

First go to your library settings and enable "Save artwork into media folders", if you have not done so already.

I believe the least intrusive way is to select "Find missing metadata" and check "Replace existing images". If that doesn't work, you will have to select "Replace all metadata" from the drop down, and also check replace existing images.

If you really want to save your images in the config folder instead of with the media files, Jellyfin will use that ID to store them in the config/data metadata folder.
You can't add the movie name there as you tried because that's not how Jellyfin saved the path in the database.

An easy way to figure out where a video is stored there is by opening the episode/movie on the web UI on a browser.
Look at the URL of the video and it will contain the ID that you need to find in the library.

Also, the metadata/library folder is sorted numerically. It uses hex numbers, so that's why it uses letters on the folder names.
