What's nice about it is that it centers the image, and you can move back and forward between them. You'll notice, however, that the coding looks wrong, but there's a number of very large errors about images in the editor; luckily I made a tutorial about that. You may have to fine tune the X position; 150 worked for my busts, but I'm not sure if it works for everything.
