151996 Add Captcha to Guestbook CGI

Have 10 year old perl guestbook script, cgi link hard-coded on 1000's of pages.

Need to alter guestbook cgi script which is posted remotely from these 1000's of pages, so that when a person submits the guestbook form a new page comes up with a Captcha to verify they are human, before allowing the guestbook entry to post.

Here's an example of the guestbook page my customers use:

[url removed, login to view]

Have included cgi file which will need to be modified(as text file)

I currently get 500 spambots a day hitting the script.. need a way to block them.

Thanks.... Simple Job for someone who knows their stuff.

Must have excellent communication skills and have positive Scriptlance feedback.
