    var canvas = document.createElement('canvas');
    canvas.width = 16 * scale;
    canvas.height = 32 * scale;
    //we assign the same classname the image has, for CSS purposes
    canvas.setAttribute('class', skinImage.getAttribute('class'));
    canvas.setAttribute('title', skinImage.getAttribute('title'));
    var context = canvas.getContext("2d"),
    s = scale;
    context.imageSmoothingEnabled=!1,
    context.mozImageSmoothingEnabled=!1,
    context.oImageSmoothingEnabled=!1,
    CanvasRenderingContext2D.webkitImageSmoothingEnabled=!1,
    context.clearRect(0,0,canvas.width,canvas.height);

    //back draw the head
    context.drawImage(skinImage, 24,  8,  8, 8,  4*s,  0*s,  8*s, 8*s);
    //back draw the body
