Hi, i am fairly new to html and i managed to create a guestbook in frontpage. It works fine except it keeps been spammed. I believe though insted of someone going on it and entering links to adult sites and others i think its some sort of automation.

I therefore wondered if i put one of those security images which displays a number then the user has to enter this i was hoping that would solve the problem.

However i havent a clue in how to make one so i have enlisted your help please.

Well, since I have no idea what kind of environment you are running (i.e. PHP/APD, MySQL database, etc., etc.) and because it appears you are just starting out and are still learning I will provide a very basic solution. To try and create your own algorithym to create those security images would be a little too advanced right now.

Just create a single code, if you will. In your form tag set the action to a javascript function such as:
action="validateForm(this);"

In the form create a text field for the password. Using the password type will replace the characters the user types with dots or asterisks. You could just as easily make it a text field:
< input type="password" name="code" >

Now create a javascript function in the head of your document to validate the value entered:
< script language="javascript" >
function validateForm(formObj) {
if (formObj.code.value = "YOURPASSWORD") {
formObj.submit;
return true;
} else {
alert("You have entered the wrong code");
return false;
}
}
< /script >
