(assuming the image files are in the relevant location and have BuildAction = Resource....)

As in my original post:
Add the png files to the project and make sure the BuildAction is set to resource. This will automatically embed the files in the EXE/DLL. You could create a folder beneath the app folder (e.g 'Images') and place the image files there. In XAML they can then be referenced simply as:

<Setter Property="Image.Source" Value="Images/save_16x16_disabled.png"/>

HTH,

P.S You could use a TextBlock instead of a Label - lighter weight.....
