I think pixelation can be caused by the software you are using to create the button images. I don't know which software you are using, I use Photoshop CS which is a professional imaging software but there are probably also cheaper, perhaps also freeware which can be used. I remember that I tried Windows Paint but had pixelation issues just like you. Try Gimp which is free, if you don't have anything else.
