Files uploading - local file links cannot be followed but one can at least inspect otherwise. If settings use s3boto with "real" values for the following settings variables, then upload and download work well:

```
DEFAULT_FILE_STORAGE = 'storages.backends.s3boto.S3BotoStorage'
AWS_ACCESS_KEY_ID="access_key_id_for_s3"
AWS_SECRET_ACCESS_KEY="secret_access_key_for_s3"
AWS_STORAGE_BUCKET_NAME="bucket-name"
```
