How to check if an image is loaded in silverlight

Question

I want to take a snapshot once an image is loaded, and here is a code snippet:

imageBrush.ImageOpened += (sender, e) => { doSomething(); };

One problem with this code snippet is that if the image brush is already loaded, the event will not be fired, so I need a way to verify that the image is already loaded but seems like there is no "IsLoaded" property in silverlight. Could you suggest an easy workaround?

You can check that an Image control's Width property is non-zero to test its loaded.

It may be therefore that you can also use the BitmapSource PixelWidth property to perform the same test:-

 bool isLoaded = ((BitmapSource)ImageBrush.ImageSource).PixelWidth == 0;

I've not tested this myself but it seems logical.
