That's true enough, but there's no way to detect if the mosaic grid is loaded. (It won't be loaded on older IE and, of course, when JavaScript is disabled.) And looks like this plug-in is already modified:

```javascript
$( '<img/>' ).load( function() {
  _self._init( options );
} ).attr( 'src', '/media/img/mosaic/loading.gif' );
```

We could use some other extensible plug-in or build our own, but I hope this change is acceptable.
