Have you thought about graying it out using opacity? If you set the opacity to about 50%, you will likely get the effect that you want. You can control how it grays by putting a rectangle of the appropriate color (white, black, gray) directly behind the image...

I've been trying to create a similar control (or one that inherits from Image) that I could use from XAML and bind its properties. The idea is that I am binding the Source property of my image instance to a property of a data type that I have created (the property is actually a string of the location in the disk of the jpg file). So I need the new control to be able to be binded to. I tried using a FormatConvertedBitmap instance as the ImageSource of the Image.Source property, and giving it a BitmapImage instance, but I couldn't bind the BitmapImage to the path of the image on the disk. I also though on creating my own BitmapEffect, which would be a better solution, but these are very complicated to write since you need to meddle with some unmanaged code and COM interfaces, so I gave up this idea. Has someone succeded in doing something similar? I would like to end up with something like a control called GrayeableImage...
