For the users skin why not do something similar to this script (not my code) which creates a human usable version of the skin.
function flip(&$img)
{
$size_x = imagesx($img);
$size_y = imagesy($img);
$temp = imagecreatetruecolor($size_x, $size_y);
$x = imagecopyresampled($temp, $img, 0, 0, ($size_x - 1), 0, $size_x, $size_y, 0 - $size_x, $size_y);
return $temp;
}
// File and new size
$filename = 'http://www.minecraft.net/skin/' . $_GET['user'] . '.png';
// Content type
header('Content-Type: image/png');
// Load
$rendered = imagecreatetruecolor(240, 480);
$source = imagecreatefrompng($filename);
$b = 120;
$s = 8;
// Fill the new image with pink and set pink as the transparent colour
$pink = imagecolorallocate($rendered, 255, 0, 255);
imagefilledrectangle($rendered, 0, 0, 240, 480, $pink);
imagecolortransparent($rendered, $pink);
// Create a flipped version of the image
