Woo hoo! Progress!

I think it was the file type that was causing the problems. But .png is a common file type and that should still have worked, so I'll investigate to see if I can fix that on NDN's end.

Arsenal - One more favor? Could you please attach another .png file for me and we'll see if it works this time around. I disabled the thumbnail (I think), so if it's working properly, we should see your full image right from the start.
