|type||The local path to the image to display.|
This function will take an image and show it on the "back" of
the wide version of the Flip type Live Tile. This image
must be an included file and not a sprite or a background,
and if it is too small or too big for the tile it will be stretched
or cropped to fit.
tile = choose("tile1.png", "tile2.png", "tile3.png");
The above code will set the "back" of the wide Live Tile to be any one of three included files.
