It all depends on your file, with the image, how you cut it ( per the image tutorial page ) etc.
If your image is a square, you can cut it just perfectly so you don't need the Alpha channel. However; if it's of another shape, you'll need to use the Alpha channel. It's what supplies the Transparency for images.
