HI Rich,
- after this command i get the messege
Error: ✗ Plugin is not supported on your architecture and os.
i am on 2.5M4 on Pi4 and Grafana v6.4.4
- Tried manual installation, but on this page https://grafana.com/grafana/plugins/grafana-image-renderer/installation the link with zip is unavailable Screenshot by Lightshot
1.0.0 https://grafana.com/api/plugins/grafana-image-renderer/versions/1.0.0/download
1.0.5 https://grafana.com/api/plugins/grafana-image-renderer/versions/1.0.5/download
It means i have no ability to render grafana images? 
PS
Manual install from this thread also gives error
