Another Gravatar Implementation

I recalled at some stage there was a Smarty Modifier called escape. I think it was when I was looking for one called rot13. Anyways, you can use this and the JavaScript function unescape() to obfuscate the email address. You’ll need this code early in your template: I stick it at the start just after <html>

    <script type="text/javascript" 
        src="http://schinckel.net/images/md5.jpg">
    </script>

This fragment will insert the Gravatar Image: 

    {capture name=reader}{comment_author_email}{/capture}
    <script type="text/javascript">
    document.write('<div class="right">');
    document.write('<img src="http://www.gravatar.com/avatar.php?gravatar_id='); 
    document.write(hex_md5(unescape("{$smarty.capture.reader|escape:"hex"}"))); 
    document.write('&size=40" alt="" />');
    document.write('</div>');
    </script>

This seems to more reliably display the Gravatars, so I’d suggest you use it instead. Either that, or Gravatar just fixed up their servers…
