### Reuseable Dashboard Urls
If the dashboard in the json file contains an [uid](/reference/dashboard/#json-fields), Grafana will force insert/update on that uid. This allows you to migrate dashboards betweens Grafana instances and provisioning Grafana from configuration without breaking the urls given since the new dashboard url uses the uid as identifer.

When Grafana starts, it will update/insert all dashboards available in the configured folders. If you modify the file, the dashboard will also be updated.
By default Grafana will delete dashboards in the database if the file is removed. You can disable this behavior using the `disableDeletion` setting.

Most Notification Channels require that this image be publicly accessible (Slack and PagerDuty for example). In order to include images in alert notifications, Grafana can upload the image to an image store. It currently supports
Amazon S3, Webdav, Google Cloud Storage and Azure Blob Storage. So to set that up you need to configure the [external image uploader](/installation/configuration/#external-image-storage) in your grafana-server ini config file.
Be aware that some notifiers requires public access to the image to be able to include it in the notification. So make sure to enable public access to the images. If your using local image uploader, your Grafana instance need to be accessible by the internet.
