The skin is currently divided into 2 sections, the front and the back.
Changing Player Skins
A player can only currently change the skin on their side, meaning if they visit an online server others will not see the custom skin. To change your skin simply replace player.png in your texture pack folder (or in the
/data/ folder if you are running 0.3.1 Stable).
Creating A Custom Skin
Creating a custom skin is simple and an easy way to customize the look of your character. Simply use your image editor of choice and create two 16x32px images, one for the front and one for the back. There is no guidelines as to what goes where, as you will never see the player from the side. Name one image player.png and the other player_back.png.
