Default Avatar doesn't link or display

Default Avatar shows up in Firefox but doesn't link while it in IE it doesn't show up at all. Entries are missing completely.

Here's a fix:

In the function:
function theme_guestbook_entry(), remove the conditional

  //if ($entry['picture']) {
    $output .= '<div style="clear:both;"></div>';
  //}

If a user is using the default avatar, it skips over the clear:both thus causing issues in both browsers.

Hope this helps.
