Richard, PhotoShop is the easiest way to do it. However if you don't have that program, go to the following site where they offer a free open source program called GimpShop. The download is about 87mb. It has most of the features of PhotoShop minus the price. GimpShop requires X11 installed on your G4. This is a sub program of OS-X that allows the installation of Unix programs. http://www.gimpshop.com/ I suspect that there are other programs out there that will do the same. Possibly other list members can make some suggestions. Hope this helps, Bill
