Animated sprite with moving gif

[Flamel]

I noticed that phaser's main webpage example code uses png file. However, I want to make an animated sprite with moving gif file. Is there anyway of doing this?

*This code is definitely not working, since it's wrong. But this was my attempt.

    game.load.spritesheet('apple', 'assets/apple.gif', 300, 300);
    //character is a sprite that I added
    var test = character.animation.add('walk');
    character.animation.play('walk', 30, false);
