Flaky PHP Jpg Upload Question

[pixelsketch]

I have a PHP script which works fine for me (I've tested a million times on MAC OSX and Windows XP running, Safari, Firefox, and IE - all work fine) the script is supposed to allow a user to browse for a JPG file on their computer, shrink that JPG, and save two copies, one at 200x200 and another small thumbanil copy.

** I HAVE PASTED THE SCRIPT BELOW**

The problem is that I have a user on a PC running Internet Explorer who needs to use this script frequently, and he says that sometimes the script will work, other times (most times) it will not. You can see a result of what his photo looks like when it is uploaded by going to:

[url=http://www.reddeerpowersports.com/uploads/33.jpg]http://www.reddeerpowersports.com/uploads/33.jpg[/url]

Now, this seems to be happening on the server?????, since the page can be accessed by him fine, and the script works fine for me. In fact portions of the script are working (ie, the image begins to upload, and all UPDATES to the database are made, but for some reason, when he tries to attach a photo, it just hangs up and gives him this half rendered image you see by visiting the above URL. 

Anyone see anything obvious??
Thank you in advance for your help,




The script is as follows:








_______PHP SCRIPT
<?
extract($HTTP_POST_VARS);
$db = mysql_connect('***********', '***********', '***********');
mysql_select_db('***********', $db);

$sql = "INSERT INTO  `forsale` (  `id` ,  `thumb` ,  `photo` ,  `title` ,  `category` ,  `details` ,  `hours` ,  `price` )
VALUES (
'',  '',  '',  '$title',  '$category',  ' $details',  '$hours',  '$price'
)";
mysql_query($sql, $db);

$numbereditem=mysql_insert_id();




if (is_uploaded_file($_FILES['file']['tmp_name'])) {
$filename=$_FILES['file']['tmp_name'];
$photoname=$numbereditem;
$thumbname=$photoname . 'thumb';
$newlargepath="http://www.reddeerpowersports.com/uploads/$photoname.jpg";
$newsmallpath="http://www.reddeerpowersports.com/uploads/$thumbname.jpg";
$badfile=1;

if ($_FILES['file']['type'] == "image/jpg" || $_FILES['file']['type'] == "image/jpeg" || $_FILES['file']['type'] == "image/pjpeg"){$badfile=0;}



$target_path = "../uploads/" . $photoname . ".jpg";
move_uploaded_file($_FILES['file']['tmp_name'], $target_path);
$source = imagecreatefromjpeg($target_path);
$width=imagesx($source);
$height=imagesy($source);
$nw=200;
$nh=(($height*200)/$width);
$thumb = imagecreatetruecolor($nw, $nh);
imagecopyresampled($thumb, $source, 0, 0, 0, 0, $nw, $nh, $width, $height);
imagejpeg($thumb, $target_path, 60);
if (!isset ($nw)){$nw=$width;}
if (!isset ($nh)){$nh=$height;}
$sql3="UPDATE forsale SET photo ='$newlargepath' WHERE `id` = '$numbereditem'";
mysql_query($sql3);

$source = imagecreatefromjpeg($target_path);
$target_path = "../uploads/" . $photoname . "thumb.jpg";


$width=imagesx($source);
$height=imagesy($source);
$nw=60;
$nh=(($height*60)/$width);
$thumb = imagecreatetruecolor($nw, $nh);
imagecopyresampled($thumb, $source, 0, 0, 0, 0, $nw, $nh, $width, $height);
imagejpeg($thumb, $target_path, 60);
if (!isset ($nw)){$nw=$width;}
if (!isset ($nh)){$nh=$height;}





$sql3="UPDATE forsale SET thumb ='$newsmallpath' WHERE `id` = '$numbereditem'";
mysql_query($sql3);

its because the user is doing soemthign that you dont count for in your code.

they may be uploading a gif, or the filesize is too large, you have to see what they are doing to cause the random behavor

the thing is though, sometimes it works and sometimes no, with the sam file, same size, same type. Did you have a look at the photo they uploaded?
