Working with images

The key assets in our game are the images to be used on the back of every tile. There will be at least as many images as the number of pairs at the highest difficulty level, plus two additional images. The first image in the list will be completely white and will be used for tiles that have been removed. The second special image will be used as a cover for every hidden tile.
