I'm still having an issue with NodeBB not being about to find a profile picture I set up on my (admin) profile. It happens on Firefox or Chrome. It's hard to discern a pattern--why some actions cause the browser not to be able to load the image, while the other still can.
I have to say that programmatically being able to show and hide content in a widget is fabulous. I now have a Global > Global Header widget that displays an image and text only when it is the "home" page.
