There's nothing like making one's Mac truely unique! I love having the ability to customize the boot image with one of my own personal pictures. It can't be any better than that. It's very easy to use, simple, straight forward. You'll love this application folks especially if you want to use one of your favorite jpg, tiff pictures etc. You can save them in the Bootx file in the library and switch back and forth if you tire of one, use another one from the file. It's that simple. Very easy to use.
