Hy!
The table is
(products(picture_p blob,prod_id number)) when i try to insert the pictureusing a similar code with this from oracle .com:

// Insert the BLOB from PHP's tempory upload area

$lob = oci_new_descriptor($conn, OCI_D_LOB);
$stmt = oci_parse($conn, 'INSERT INTO BTAB (BLOBID, BLOBDATA) '
.'VALUES(:MYBLOBID, EMPTY_BLOB()) RETURNING BLOBDATA INTO :BLOBDATA');
oci_bind_by_name($stmt, ':MYBLOBID', $myblobid);
oci_bind_by_name($stmt, ':BLOBDATA', $lob, -1, OCI_B_BLOB);
oci_execute($stmt, OCI_DEFAULT);

// The function $lob->savefile(...) reads from the uploaded file.
// If the data was already in a PHP variable $myv, the
// $lob->save($myv) function could be used instead.
if ($lob->savefile($_FILES['lob_upload']['tmp_name'])) {
oci_commit($conn);
}
else {
echo "Couldn't upload Blob\n";
}
$lob->free();
oci_free_statement($stmt);

// Now query the uploaded BLOB and display it

$query = 'SELECT BLOBDATA FROM BTAB WHERE BLOBID = :MYBLOBID';

$stmt = oci_parse ($conn, $query);
oci_bind_by_name($stmt, ':MYBLOBID', $myblobid);
oci_execute($stmt, OCI_DEFAULT);
$arr = oci_fetch_assoc($stmt);
$result = $arr['BLOBDATA']->load();

// If any text (or whitespace!) is printed before this header is sent,
// the text won't be displayed and the image won't display properly.
// Comment out this line to see the text and debug such a problem.
header("Content-type: image/JPEG");
echo $result;

oci_free_statement($stmt);

oci_close($conn); // log off
}
?>
