Ok, so Im just learning this whole texture set thing. So, I decided I'd start off by some experimenting. So, I made a 128x128 acid colored square, with a tribal sun in the middle. This is the texture for every part, except the head. The thing is, the textures on the left and right of the tori aren't symmetrical. I've no clue how to go about doing this, whether it be flipping the picture somehow, or what. So, can someone let me know how to reflect the texture from one side, onto the other?

Heres a pic:
