How to Prevent Plex from Changing Movie Posters

When Plex updates the metadata for movies on your server it may also change the movie poster to one it finds online. If you have carefully set your posters for your movies this can be frustrating to have Plex change the posters.

To prevent this from happening, there are a few things you can do in Plex to keep your own selected posters from being changed.

The next few sections will describe the methods you can use to keep your movie posters from being changed by Plex.

How to Prevent Plex from Changing Movie Posters

Storing and using your movie posters

The first method is simply to store the movie poster in the same folder as your movies, and then have Plex use that poster.

This works best when you each of your movies in its folder, that way it keeps things organized on your hard drive.

Poster naming conventions

To store posters in a folder containing a single movie, you would use the following poster naming convention:

Movies/MovieName (Release Date)/PosterName.ext

The PosterName value can be one of the following:

  • cover
  • default
  • folder
  • movie
  • poster

For example, for The Godfather, you would do something like the following:

Movies
    /The Godfather (1972)
        /The Godfather (1972).mkv
        /poster.jpg

You can still store your posters even if all your movies are in a single folder.

The naming convention for movie posters stored in a single movies folder is as follows:

Moves/MovieName (Release Date).ext

For example, The Godfather (1972).jpg would be the name of a poster for The GodFather.

You can have multiple posters for a movie by appending a number after the file name, such as:

poster-1.jpg

or

The Godfather (1972)-1.jpg

The first poster doesn't need a number appended, however, any additional posters should include a number.

If you have carefully set your movie posters and would like to download them, you can use the script documented in How to Download Movie Posters from Your Plex Server.

Enable local assets Plex movie agent

Once you have the poster files added to the same folder as your movie files, you will need to enable the movie library in Plex to use the local assets.

To do that, use the following steps:

  1. Log into your Plex server as an administrator, and then hover your mouse over the movie library you wish to edit, click the three dots, and then select the Manage Library->Edit... option.
    Plex Edit Movie Library Option.
    The Plex edit movie library option
  2. From the Edit Movies dialog, click the Advanced option on the left, then scroll down and click the Use local assets checkbox, and then click the Save Changes button.
    Enabling the Use Local Assets Option for a Movie Library
    Enabling the 'Use Local Assets' option for a movie library

After doing the above steps, Plex will now use the local posters for your movies instead of the ones it downloads from the Internet.

Locking the movie posters using the Plex API

Sometimes the reason Plex may change movie posters is because the posters aren't "locked."

When you make changes to metadata for a media item in Plex, you will notice that a lock icon beside the field you change changes from a gray color to an orange color.

An orange lock means the field has been "locked" and indicates that Plex won't update that field when metadata for that media item is refreshed.

There is no lock indicator for movie posters in Plex, so you can't manually enable the lock on a poster.

You can use the Plex API to lock the poster by calling the Update Movie Details API command.

The steps to lock the movie poster using the Plex API are as follows:

  1. Call the Get Libraries API to find the key associated with the movie library.
  2. Get the key of the movie by calling the Get All Movies API command.
  3. With both the movie library key and the movie key, you can lock the movie poster for the movie using the following command:
    curl -X PUT http://{ip_address]:32400/library/sections/{library_key}/all?type=1&id={movie_key}&thumb.locked=1&X-Plex-Token={plex_token}
    import requests
    plex_url = http://{ip_address}:32400/library/sections/{library_key}/all?type=1&id={movie_key}&thumb.locked=1&X-Plex-Token={plex_token}
    response = requests.put(plex_url)
    print(response.text)
    $response = Invoke-RestMethod 'http://{ip_address}:32400/library/sections/{library_key}/all?type=1&id={movie_key}&thumb.locked=1&X-Plex-Token={plex_token}' -Method 'PUT'
    Write-Output $response

If you would like to lock the posters for multiple movies you will need to get all the keys for the movies from step 2, and then run the command in step 3 for each movie.

Using Plex Meta Manager

Another method of preventing Plex from changing your movie posters is to setup and use Plex Meta Manager

Plex Meta Manager is a popular tool for managing metadata for your media libraries, including managing posters. You can even display overlays over your posters that can display specific information about the movie.

I don't currently use this tool, but I have heard good things about it, so may check it out someday.

At this time, though, I like to keep my Plex installation simple to prevent me from having to perform too much maintenance on it.

The above sections provided different methods of preventing Plex from changing the movie posters that you have set up yourself. If you have carefully curated your posters, you can try one of the methods to protect the time you have spent to make Plex the way you want.
