Licensee states .jpeg was created using Paint Shop Pro.

Chris-As a followup to our discussion, and your request feed; here's the reply:
Licensee states their customer's view is that since IE and Netscape ca both handle the image (and there are other similar ones that the customer has produced, also using PaintShopPro), then the Sun JDK should also display whatever it can.
