I believe that BLOBs can't be handled as strings. You will need to use
http://www.php.net/manual/en/pdostatement.bindvalue.php
OR
http://www.php.net/manual/en/pdostatement.bindparam.php
Unfortunately I cannot give detailed instructions since I use the SQLite3
interface for PHP rather than the PDO one.
