Hello,
I followed the instructions on this page: http://www.zenphoto.org/support/topic.php?id=1129&replies=1

and set up an akismet filter . The problem is that whatever I post ,it is flagged as spam.It doesn't get posted.(I have a valid API key)
I'm testing my zenp on my local machine.So my blog url is set to http://localhost/album .Could that be the problem(comments from localhost are treated as spam)?

Ps:The readme in the zip file mentions the function addComment(...) in classes.php but it was in class-image.php.I'm using the latest stable build on a lampp install.

Here's the code:
`

$zp_gal_url = 'http://localhost/album/';

$zp_akismet_key = '.....';

$this->getComments();

$name = trim($name);

$email = trim($email);

$website = trim($website);

// Let the comment have trailing line breaks and space? Nah...

// Also (in)validate HTML here, and in $name.

$comment = trim($comment);

if (empty($email) || !is_valid_email_zp($email) || empty($name) || empty($comment)) {

  return false;

}

if (!empty($website) && substr($website, 0, 7) != "http://") {

  $website = "http://" . $website;

}

require_once 'Akismet.class.php';

$commentData = array(

          'author'    => $name,

          'website'   => $website,

          'body'      => $comment,

          //'permalink' => $this->getFullImage()

     );

$akismet = new Akismet($zp_gal_url, $zp_akismet_key, $commentData);

//if($akismet->isError()) {

//   echo'Couldn't connected to Akismet server!';

      // TODO: Add more precise error handling

//} else {

     if($akismet->iscommentspam()) {

         // TODO: Add Spam Moderation Capabilities

         //echo'Spam detected';

     } else {

         //echo'Not Spam!';

         $newcomment['comment'] = $comment;

         $newcomment['date'] = time();

         $this->comments[] = $newcomment;

         // Update the database entry with the new comment

         query("INSERT INTO " . prefix("comments") . " (imageid, name, email, website, comment, date) VALUES " .

I'll work on getting this updated after I'm done updating my JoshuaInk theme.

Try it again. http://www.gamedudex.com/2007/01/18/akismet-hack-for-zenphoto/

I updated the readme to reflect the correct location of the code for ZenPhoto 1.0.8. Make sure you start off with a fresh version of your class-image.php.
