With no rows returned, there's no array. The while() loop doesn't
even trigger there.
You could either add some dummy data, populate the rows, or adjust
the code like so:
<?php
if (isset($thumbsarray) && is_array($thumbsarray)) {
while (list($key, $value) = each($thumbsarray)) {
// ...
}
} else {
// There are no thumbs. Oh, my God, the horror! No thumbs!
}
?>
