I can also confirm that pressing escape will cancel the poster dialogue box, but not the file browser; further press “back” or the directory breadcrumbs in the file browser also does not do anything.
I cannot replicate this behaviour anymore in the current version of Plex for Windows 1.60.1
Also, I urge you to NOT add posters in this way to your media.
(the only exception being playlists and collections)
But for all other media types you really should store the posters as “local assets” beside the media files.
The rules for naming them can be found here: https://support.plex.tv/articles/categories/your-media/
Thanks. I will force a client upgrade and see if that resolves it. I typically use the client’s edit metadata → Poster option because it circumvents transcoding loss from saving the poster to an image site (or TheTVDB/TheMovieDB) and then entering it from there via URL. Is there actually a negative issue with loading a poster this way? I assumed local file posters are cached into the database on scrape anyway.
Yes, a very important one: if you have for some reason to rebuild your library (let’s say a defective hard drive in your server), you’ll have to do all this work again. And they are only stored inside the Plex data folder. You usually don’t have a second backup of all those posters, so you’d have to go on the hunt for the right motives again.
If you instead place them as .jpg files directly beside your video files, Plex server will read them directly from there and also select them as default (with the right library preferences).
And they are backed up together with your media files (I assume you are doing backups of these, right?)
