I am attempting to add images using the GetPicture method of the OfficeViewModelBase class, but I keep encountering a Word error stating "Can't find the callback 'GetPicture'." Even when I attempt to create my own callback and reference it in the loadImage attribute in the XML, it doesn't seem to work. This approach works fine on a non-VSTOContrib XML ribbon.
