Interestingly enough, it's possible to actually insert an image into Netscape's view source page instead of just having text. When Netscape users view the source of your page, they see an image as well as the source code! Your image could tell the visitor that they are not allowed to view this source code, for example.
New Links Displaying links as new for a few weeks after adding them is great. But, adding, removing, and updating that "New" icon for each link is pointless! Let JavaScript do your work for you!
