        $imageData = mysql_real_escape_string(file_get_contents($_FILES['image']['tmp_name']));
        $imageType = mysql_real_escape_string($_FILES['image']['type']);

        echo $imageName;


        if(substr($imageType,0,5)=="image"){
            mysql_query('insert into image values("","$imageData","imageName")');
        }
        else echo "Select Image to Post";
    }
?>
