Tv episode thumbnails not recognised

[Atlantiantokra]

The setting you're talking about forces jellyfin to use the episode primary image for every episode of every TV show regardless of any other images associated with them.
"episode filename-thumb.jpg" despite the tag -thumb is not the thumbnail image anymore it is the primary image.

In the screenshot I've attatched there is the textless primary image and the thumb with the episode title.
Previously the file path jellyfin created after adding the images manually were:

• Primary - \tvshow\season\metadata\episode filename.jpg
  
• Thumb - \tvshow\season\episode filename-thumb.jpg
  

After updating the jellyfin created paths are now:

• Primary - \tvshow\season\episode filename-thumb.jpg
  
• Thumb - Unknown
  

Without using the setting jellyfin looks for images to use in a specific order.
episode-thumb >show-thumb>season thumb>show backdrop>show primary
image with title>show-thumb>season thumb>show backdrop>textless image

Because I don't know the new path that jellyfin is expecting for episode thumbnails I have to add them manually in the UI for each episode one at a time, jellyfin still uses thumbnails in the same way it just doesn't recognise the old file path as a thumbnail anymore.

edit: corrected file priority order and added season thumbs
