Usage

Running the command tries to find the Steam screenshots directory and uploads any screenshots to Immich. The game name will be put in the description of the image.

Optionally, you can specify an album in which the screenshots should be added.

Running the command again will only upload new screenshots since it saves the state locally.

You could automate uploading with a cron job or somehow run it at Steam startup. But thats outside the scope of this software.
