I just made the changes in the readme file.  The image shows, I tested a sample signature, and it just says:

The Image Verication code you supplied is incorrect.
Please enter the 8 characters that appear in the image.

What did I do wrong?

(isset($_POST["gb_action"]))
NOT
(isset($HTTP_POST_VARS["gb_action"]))

  '   You forgot to fill in the Name field. Please correct it and re-submit.  '

Personally I recommend my human verification over this but horses for courses. $_POST is the new way of doing $HTTP_POST_VARS so simply replace one with the other. It sounds like you forgot to add the code to addentry.php.

I have forund the problem it was in addentry.php

Currently going through a very bad patch of spam posts, let hope the image solution fixes it

Thanks for the quick response

Ok just a quick message. You need to reopen form.php and delete
<!--  <tr bgcolor=&quot;#E8E8E8&quot;>
    <td width=&quot;25%&quot;><div align=&quot;left&quot; class=&quot;font2&quot;>HTML code is disabled<br>Smilies are ON<br>AG Code is OFF</div></td>
-->

next delete one of the two <td>'s you have just below that before
<input type=&quot;submit&quot; name=&quot;
This will fix the layout.

Hi carbonize you're making a great job against the f...... spammers,  I really like the image verification mod, but i'm asking if is posible instead of echo:

    if (isset($HTTP_POST_VARS[&quot;gb_action&quot;])) {
          if (strtoupper($_POST[&quot;keycode&quot;])!=$Vword)
         {
              echo (&quot;The <strong>Image Verication</strong> code you supplied is incorrect.<br />\nPlease enter the 8 characters that appear in the image.&quot;);
              echo $gb_post->process();
              die();
         }

make a dialog box, showing the error?

Thanks

PLEASE TRY THE SIMPLE ANTI SPAM SOLUTION BEFORE TRYING THIS ONE
Sites using the Advanced Guestbook have been plagued by spammers using automated scripts to post stupid entries with links to their websites. You stop this by using the image verification script made by Freddy and myself. You can get it from http://carbonize.co.uk/verification.zip .

I did all this and checked it several times.

the result :

Parse error: parse error, expecting `T_VARIABLE' or `'$'' in /fysical path to guestbook/guestbook/lib/add.class.php on line 324

Fatal error: Cannot instantiate non-existent class: addentry in /fysical path to guestbookguestbook/addentry.php on line 11

Any ideas ?
