I use the skins off of Skinseed that are 132x132. For some reason on the legs, when looking at it, the bottom layer is of the left leg is mirrored on the other leg (even if they're different) and the top layer stays the same... it does that only on the 132x132 and not the original 64x64. The original skin is a slim-armed skin and the legs are wrong... but somehow the arms stay the same and the legs are correct on the original-armed skin.
