For best results, make your image file 256 by 256, but only place content in the upper left 200 by 200 area. This area is then rendered at a 0.5x scale compared to the rest of the book in pixel size.

Does not work. My picture is 256 by 256. Picture with 200 by 200 is the same problem.

200x200 content in a 256x256 image, or just an 200x200 image? Read the docs again please
