hi guys i really need some help with this i just cant get my head round it i have two tables emails and filesEMAILS has id, from, subject, body, dateFILES has id, email_id, filename, mime, subject i need to display the email body and IF it had a picture attached to the email it will have the details logged in files so here's what i have so far

$result = mysql_query("SELECT * FROM emails WHERE subject = '$id' ORDER BY date DESC LIMIT 2");echo date('H:i:s', time());echo '<br>';while($row = mysql_fetch_array($result)) {$result2 = mysql_query("SELECT * FROM files WHERE subject = '$id' ORDER BY id DESC LIMIT 2");while($row2 = mysql_fetch_array($result2)) {  if($row2['email_id'] == $row['id']) {   echo '<img src="uploads/'.$id.'/thumbnail/'.$row2['filename'].'" style="border:0px">';   echo $row['from'];   echo $row['body'];   echo '<br>';  } else {   echo '<img src="images/avatar.png" width="100px" style="border:0px">';   echo $row['from'];   echo $row['body'];   echo '<br>';  }}}

SELECT * FROM files WHERE email_id IN (SELECT id FROM emails WHERE subject = '$id' ORDER BY date DESC LIMIT 5)
