I'm using node-notifier (link) in node.js to show a toast notification in Windows 8. I have it working and I'm able to adjust the title, text, and main image in the notification just fine. However, in a Windows 8 toast notifications, there is a secondary (smaller) image. See below:
So, node-notifier uses toaster, which in turn uses ToastNotificationManager. But, I cannot find any reference anywhere to this secondary image. I've looked here and here on Microsoft's site.
This secondary image also shows in other notifications I receive from applications like Outlook, Slack, etc.
Where is this secondary image coming from? Is the documentation just out of date? Can Toaster be modified to access this secondary image?
