Here are the 2 raw images that I have used so far that look decent displayed on the unit. High-res, close up images tend to work best because when the unit stores them as a wallpaper, it automatically reduces the file size, so when it is actually displayed as a wallpaper, the image is more pixelated than the raw image. So, the higher the resolution of the original image and the larger it is, the better it ends up looking as a wallpaper. Unfortunately, there is no way of stopping the unit from compacting the file to keep full resolution.
