Create a DisableableImage class that is a typical WPF control. Inside, place two elements: the image, and a rectangle that appears only when the control is disabled.

With a color of gray and an alpha of somewhere around 40%, you should get an effect similar to actually graying out the image -- without all the effort to actually modify the image itself.
