I am writing this code :

<?php foreach($daftargambar->result() as $row){
$filename = $row->file_name;
$mime_type = $row->mime_type;
$filedata = $row->file_data;
header("content-disposition: inline; filename=$filename");
header("content-type: image/jpeg");
header("content-length: ".strlen($filedata));
echo ($filedata);

}
