Comment 8 for bug 1542083

The removal of fallback art is currently in silo 45. When that lands, the blurry icon will disappear and you'll be left with a blank rectangle.

If you want to display something other than an empty rectangle set an onStatusChanged handler on the Image component, and if status changes to Image.Error, set source to the desired fallback image. This will allow you to pick a fallback that is appropriate to your app.

We're removing the fallback feature because (a) it is impossible to return a fallback image that is optimal in all situations (where some apps use a light background and others dark), and (b) it is currently impossible for applications to detect when a fallback image has been substituted other than reading the pixels of the Image component.
