You may have updated your PHP lately. The image with wo-worldmap is 'broken' due to a PHP error message
<br />
<b>Deprecated</b>: The each() function is deprecated. This message will be suppressed on further calls in <b>/home/meteotorkc/www/saratoga/whos-online/wo-worldmap.php</b> on line <b>333</b><br />
In wo-worldmap.php (and maybe others) change
while (list($numl, $line) = each($lines)) {
to
foreach ($lines as $numl => $line) {
to fix the code.
