Just a note of thanks to the GrandNode team for making the Azure CDN integration so simple to get up and running.  I set 3 AzureBlob config variables in appsettings.json, and it just worked.  All images are now automatically uploaded to blob storage, saving us disk space on the web server.  Images & thumbnails on the front-end are being served up from the Azure CDN.  Very impressed.

We always try to implement the simplest and the most usable solutions, thanks for your kind words.
