I have installed the new plugin for image rendering in Grafana, but it doesn’t work.
Grafana version:8.2.1
Have installed chromium browser and all the Linux libraries related to it, still image rendering doesn’t work. Please help.
What errors are you seeing in the Grafana server log?
Hi,
Please find the logs.

I don’t see any error related to image rendering.
Also I am running the open source version so license error is not relevant here.
Can you describe how it isn’t working if you are not getting an error message?
Hi,
My alert notifications do not have the image in it.
Can you please help me link the images with the alerts?
I am using Grafana 8.2.1 and it doesnt have include image option like it did in the earlier versions.
Thanks
Also I am trying to do image rendering using docker-compose.yml.
When I tried to build it, I am getting following error.

Image rendering in notifications is not supported in Grafana 8 alerting. The short reason for this is, alertmanager.
The longer explanation is that we embed an instance of alertmanager to handle notifications in the new alerting system. Because alertmanager doesn’t support images, we are also not able to do so. The feature has been discussed by the alertmanager folks and, so far, they have elected to not support the feature. This doesn’t mean we will never support this again, just trying to lay out why, as of today, it’s not an option. The best thing you can do is add your voice to one of the feature requests for this.
