Try clearing your browser's cache. Often times browsers cache the old
image and don't bother to look at the new one. If this isn't the
problem, the only thing I can think of is to check if the file exists
(http://us3.php.net/manual/en/function.file-exists.php) and delete it
before the move (http://us3.php.net/manual/en/function.unlink.php).

Hope that helps.
