replacing a spritesheet in the preload() function

[Nek0]

looking for a way to replace a preloaded spritesheet's image file. something like:

game.load.spritesheet('player', 'img/player.png', 32, 64)

changes to:

game.load.spritesheet('player', 'img/player2.png', 32, 64)

i've tried calling the second line after the preload function but it doesn't seem to work.

nevermind. this seems to do it:

game.load.spritesheet('player', 'img/player2.png', 32, 64)
game.load.start()
