Yuck.
img.onerror = function () {
this.onerror = null;
this.src = 'images/imagenotfound.png';
};
Obviously the compatibility of this is at least as good as the compatibility
of the original code.
However, for this to work reliably, as always, the event listener has to be
defined *before* the property is changed that can fire the event:
img.onerror = …;
img.src = 'images/' + name + '.jpg';

Unlikely.
