I would probably put the actual image files in each app. I don't think you get much value out of trying to embed them in the PCL.

In your portable ViewModels, you can reference the image via a Uri. Unfortunately that Uri needs to be different on each platform. For Windows Store apps it needs to be something like ms-appx:////Assets/image.png where for Windows Phone I think it will just be /Assets/image.png.

So you'll need some code to figure out the correct Uri format. That could be a platform-specific service with a portable interface that the ViewModels would call. You might also be able to create a binding converter that would do whatever conversion you needed.

There are certainly other ways of doing this-- this is just what I'd picked based on the information in your question.
