David: I'm not sure why you cant get the link to work. Its working fine from here?! Try going to
http://ciclops.org/ir_index.php?id=3 and then clicking on "The Greatest Jupiter Portrait".
Slice: Unsharp masking the original photo brings out more detail as well which is cool!
eg.
Original:
http://www.users.on.net/~sjeriksson/...ce/79_50_1.jpg
Unsharp mask:

It looks great as a desktop background (resized to suit)!
