With the graphical counter script completed, you are ready to add the graphical access counter to your Web page. As with the text access counter, you need to create and seed the count.dat file. If you didn't follow the text access counter example, read the section "Seeding the Counter" earlier in this article. The graphical access counter is called from the <IMG> HTML tag. The line
<IMG SRC="/cgi-bin/graphical-counter">
calls the graphical-counter file and displays the results returned from the script. Listing 9 contains the HTML code for an example using the graphical counter script, and Figure 4 shows how the page would appear in the Netscape browser.
