Preview image for photos

[ipod86]

Hello, 

I have been using emby so far and would like to switch to jellyfin.  
In addition to music, I also often looked at photos via emby.  
I have already integrated these into jellyfin.  Unfortunately, I find it very annoying that the folders with the images do not have preview images.  Can I set this somewhere?  
Can't find anything.

AFAIK, there is no way to do this automatically. Just "Edit Images" and adding them manually.
