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 funkwhale-manage command line interface to generate new thumbnails. If you want to keep thumbnails at their original quality, add THUMBNAIL_JPEG_RESIZE_QUALITY=70 to your .env file.

Note

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

To generate new thumbnails:

Debian

SSH into your Funkwhale server.
Navigate to your Funkwhale directory.
```
cd  /srv/funkwhale
```
Delete the __sized__ directory inside your MEDIA_ROOT directory. By default this is /srv/funkwhale/data/media. This directory contains the current thumbnails.
```
rm -r __sized__/
```
Run the funkwhale-manage command line interface to regenerate the thumbnails.
```
venv/bin/funkwhale-manage fw media generate-thumbnails
```

Docker

SSH into your Funkwhale server.
Navigate to your Funkwhale directory.
```
cd  /srv/funkwhale/
```
Delete the __sized__ directory inside your MEDIA_ROOT directory. By default this is /srv/funkwhale/data/media. This directory contains the current thumbnails.
```
rm -r data/media/__sized__/
```

Run the funkwhale-manage command line interface to regenerate the thumbnails.

docker compose run --rm api funkwhale-manage fw media generate-thumbnails

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