 ### Local image server
 
-Arkindex splits up image URLs in their image server and the image path. For example, a IIIF server at `http://iiif.irht.cnrs.fr/iiif/` and an image at `/Paris/JJ042/1.jpg` would be represented as an ImageServer instance holding one Image. Since Arkindex has a local IIIF server for image uploads and thumbnails, a special instance of ImageServer is required to point to this local server. In local developement, this server should be available at `https://localhost/iiif`. You will therefore need to create an ImageServer via the Django admin or the Django shell with this URL. To set the local server ID, you can use the `LOCAL_IMAGESERVER_ID` environment variable or set a custom setting in `local_settings.py`:
