Execute a delegate only once

MySchizoBuddy · April 2007

if($Context->SelfUrl == 'comments.php'){

function Render_CommentImage (&$CommentGrid) {

$Comment = &$CommentGrid->DelegateParameters['Comment'];
$Comment->Body = '<div>IMAGE</div>' . $Comment->Body;
}

$Context->AddToDelegate('CommentGrid', 'PostCommentOptionsRender', 'Render_CommentImage');
}

I want this delegate to run just once for the very first comment, and never run again
