|fname||The local path to the image to display.|
This function will take an image and make it the "large" icon of
the Iconic 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
tile = choose("tile1.png", "tile2.png", "tile3.png");
The above code will set the large Iconic Live Tile to be any one of three included files.
