Creating Alpha PNG Images in Paint Shop Pro 7

1. Create an image
2. Create a mask (this is the alpha layer)
3. Save the mask to an alpha channel
4. IMPORTANT: Delete the current mask, and don't merge it into the current layer. If you don't do this, the resulting image will be double-alphad.
5. Save the image to a PNG file.
