I've got this definition in my XAML:

<Image Name="AlbumArt" Source="/AlbumChooser2;component/Resources/help.png" />

The image is display OK on startup.

In my code I'm looking for mp3's to play and I display the associated album art in this Image. Now if there's no associated image I want to display a "no image" image. So I've got one defined and I load it using:

BitmapImage noImage = new BitmapImage(
              new Uri("/AlbumChooser2;component/Resources/no_image.png",
                      UriKind.Relative));

I've got a helper class that finds the image if there is one (returning it as a BitmapImage), or returns null if there isn't one:

if (findImage.Image != null)
{
    this.AlbumArt.Source = findImage.Image; // This works
}
else
{
    this.AlbumArt.Source = noImage; // This doesn't work
}

In the case where an image is found the source is updated and the album art gets displayed. In the case where an image isn't found I don't get anything displayed - just a blank.

I don't think that it's the setting of AlbumArt.Source that's wrong, but the loading of the BitmapImage.

If I use a different image it works, but if I recreate the image it doesn't work. What could be wrong with the image?
