**What happened**: I follow Slack docs and try to use Slack apps for intergrating. So I created a Slack app for notification. I can send alert to slack channel, but this alert doesn't include image. > Instead, we suggest that you read about their replacement - Slack apps. Slack apps can be built just for your own workspace or distributed through the App Directory, and they can use the latest and greatest APIs and UI features. > https://api.slack.com/custom-integrations If I try to use old incoming-webhook version of Slack https://slack.com/apps/A0F7XDUAZ-incoming-webhooks, everything is ok. I can send alert with image. I setuped `external_image_storage.s3`, rendering image is ok, uploading image to s3 bucket is ok (checked in s3 bucket + open s3 url in browser) **What you expected to happen**: - Want to use Slack apps for notification. I think Slack will remove old version in feature. **How to reproduce it (as minimally and precisely as possible)**: Slack: - Create a slack apps - Enable incoming-webhook - Get bot token Grafana: - Setup `external_image_storage.s3`. Eg: ``` [external_image_storage] provider = s3 [external_image_storage.s3] bucket = grafana-bucket region = us-west-2 path = dashboard access_key = xxxxxxxxxxxxxx secret_key = xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx ``` - Setup alerting in Grafana dashboard ![image](https://user-images.githubusercontent.com/1505720/70198731-3d2f1e80-1742-11ea-80aa-ef69082b5672.png) **Anything else we need to know?**: **Environment**: - Grafana version: 6.5.1 - Data source type & version: - OS Grafana is installed on: Ubuntu 18.04 - User OS & Browser: macosx + firefox - Grafana plugins: just `grafana-image-renderer` replace phantomjs - Others:

Here are the logs from grafana container
