When visitors using Netscape right-click your web page and select "View Source" or go to the View menu bar and select "View -> Page Source" the entire source code of your page is displayed. 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. A very simple but very clever script, indeed.
