My setting for the picture would be like this: Set the picture in both diffuse and ambient channel. Set ambience to 100% and set diffusion to the brightness of the picture. Then edit the ambience untill you get the brightness you want. This creates a very vivid texture, just like you would expect from a pinball machine.
