How can you use XML to provide content (like images) to a WPF Application?

If I had a WPF application that has a bunch of static images, text, and other things of the sort. Would there be a way to change this content through XML rather than having to change it through the XAML every-time?

For example, is this possible:

<Image Source="{ xml written path to image }" />

? If so, how.
