Please add a TODO comment about using the proper base URL here.  If don't have
base URLs quite figured out yet, so it's not something we need to fix right now.

We'll eventually need a notification pathway for when the image load is complete
so that we know to repaint, etc.  Maybe add a TODO comment for now?
