Regenerate thumbnails

We increased the quality of thumbnails from 70px to 95px in Funkwhale 1.0. This action removes visual artifacts that affect lower quality thumbnails. You can run the manage.py script to generate new thumbnails. If you want to keep thumbnails at their original quality, add THUMBNAIL_JPEG_RESIZE_QUALITY=70 to your .env file.

If you're using S3 storage, the `__sized__` folder is located in your S3 bucket.

To generate new thumbnails:

1. SSH into your Funkwhale server.
2. Navigate to your Funkwhale directory.

      ```{code} bash
      cd  /srv/funkwhale
      ```

3. Delete the `__sized__` directory inside your `MEDIA_ROOT` directory. By default this is `/srv/funkwhale/data/media`. This directory contains the current thumbnails.

      ```{code} bash
      rm -r __sized__/
      ```

4. Run the `manage.py` script to regenerate the thumbnails.

      ```{code} bash
      poetry run python manage.py fw media generate-thumbnails
      ```

1. SSH into your Funkwhale server.
2. Navigate to your Funkwhale directory.

      ```{code} bash
      cd  /srv/funkwhale/
      ```

3. Delete the `__sized__` directory inside your `MEDIA_ROOT` directory. By default this is `/srv/funkwhale/data/media`. This directory contains the current thumbnails.

      ```{code} bash
      rm -r data/media/__sized__/
      ```

4. Run the `manage.py` script to regenerate the thumbnails.

      ```{code} bash
      docker-compose run --rm api python manage.py fw media generate-thumbnails
      ```

The script generates new thumbnails for all album and artist art on your pod.
