+### Server side image rendering
+
+Server side image (png) rendering is a feature that is optional but very useful when sharing visualizations,
+for example in alert notifications.
+
+If the image is missing text make sure you have font packages installed.
+
+```
+yum install fontconfig
+yum install freetype*
+yum install urw-fonts
+```
