Load image from file to dynamic resource programmatically

Question

I need to load an image file to WPF's dynamic resource programmatically because the directory which contains the image files can be moved.

How can I load an image to WPF's dynamic resource which is used like this: Source="{DynamicResource ...}" in XAML?

In XAML:

<Image Source="{DynamicResource MyDynamicImage}" />

In code:

var myimg = new BitmapImage(new Uri("SomeUriHere"));
Resources["MyDynamicImage"] = myimg;

(The Resources collection should be one which is in the scope of the Image of course, if you have a direct reference to the Image control you can also use the immediate Image.Resources)

Whenever you set a new object to that resource key the DynamicResource will update.
