Take a league file export from Basketball GM or any of the other ZenGM games, and generate a folder containig images of all the players, in PNG format.
First install Node.js and then you can run it like:
npx @zengm-games/export-faces --league BBGM_League_1_2025_preseason.json
By default that will export the current active players on their current teams, to a folder named "exported-faces".
You can also specify a couple additional options to customize this behavior.
Use the --season option to pick a season of faces to export, rather than current active players:
npx @zengm-games/export-faces --league BBGM_League_1_2025_preseason.json --season 2024
And use the --folder option to pick a different folder for the PNGs:
npx @zengm-games/export-faces --league BBGM_League_1_2025_preseason.json --folder my-folder
