You can display the actual Perl script with the link below. You can then save it to your local computer. It should be on your system, if not see the Webmaster's Virtual Bookcase. The only difference between this HTML and conventional HTML is variable substitution. There are several variable replacements.
Lets bring it all together.
Transfer big-pic.pl to your cgi directory. Insert the link to the Perl script, including the query string, in your HTML document as shown above. Test the script. Don't forget to let me know if you used the graphical viewer so we can give you a free link. Also, let me know what else you would like to see on these pages.
