A simple app made as an example of how to load a user's profile picture using the API provided here. I made this a long time ago, however, it still works like it should. You'll see that it's named "Theme Switcher Sample", but just ignore that (I have no idea why I named it that).
This will probably be pointless to the average KAG player, but this should help out KAG developers if they're making something in .NET.
