Desktop wallpaper. 1) Lots of empty space for placing icons without obstructing the user's view of the ladies. 2) If the user wants to horizontally flip the picture and place icons on the left side instead of on the right, the lack of text and logos means no weird-looking backwards lettering.
And all that empty unbalanced space can be easily cropped out anyway if the user doesn't care about using the image as wallpaper.
