What you will want to do is upon upload you will want chekc the database first to see if the picture file name is already in the database and if so just use the UPDATE statement or if the file doesn't exists use the INSERT statement intsead.

why doesn't this one works..
[code]

<?php
session_start();
include 'db.php';
$dir="userpic/";
$actuser=$_SESSION['username'];

if(isset($_POST['upload']))
{
$checkpic="SELECT username FROM userpic  LIMIT 1";
$query7=mysql_query($checkpic);
while($checkuser=mysql_fetch_array($query7)){
if($checkuser > 0){
$query00=mysql_query("UPDATE userpic WHERE username='$actuser'");
if(!query00){ echo"error";
}
}else{


if ($_FILES['ulfile']['type']!="image/pjpeg") {echo"that kind of file is not permitted please only use jpg images.";
exit();
}
if($_FILES['ulfile']['name']==""){echo"at least pic a picture man!";
}
$filename = $_FILES['ulfile']['name'];
$tmpname = $_FILES['ulfile']['tmp_name'];
$filesize = $_FILES['ulfile']['size'];
$filetype = $_FILES['ulfile']['type'];
$datetime = date('m-d-y h:i:s');

$filepath = $dir . $filename;
$result=copy($tmpname, $filepath);
if(!$result){ echo " a problem occur";
}
$sql2=mysql_query("INSERT INTO userpic (name,username,datetime, size, type, path)VALUES('$filename','$actuser','$datetime','$filesize', '$filetype', '$filepath')") or die(mysql_error());
header('Location: testphp/');
}
}
}
?>
