Image is not coming in grafana alert email notification

Hi All,

I am not getting image in the Grafana Alert notification email… i have downloaded the grafna image render zip file onto “/var/lib/grafana/plugins” path and unziped it (as i was not able install this image render through “grafana-cli” )

I have installed Prometheus and Grafana on same Ubuntu server.

Ubuntu version: 20.04.1
Grafana Version: 7.3.2
Prometheus Version: 2.22.1
Image render plugin version:

i think the reason for error is the server_url specified in above rendering sectin is not up and running. how to make that url up…

Error Log from Grafana.log file

Below are my My rendering settings in /etc/grafana/grafana.ini file
server_url =
callback_url =
concurrent_render_request_limit = 30

Please help with above issue…

Did you already install the package that needed for image rendering?

Also you need to install chromium-browser.
