Assuming you can get the user id into a variable called $userId, you can change the $n variable as was previously suggested.

$timestamp = time();
$n = "image/$userId_$timestamp.$ext";

When you execute the move_uploaded_file() method, the file will be moved into the image directory relative to the location of your upload script. You might want to make sure that the image folder already exists, and is writable.

you can use uploadify because:

  • Multiple File Uploads
  • Drag and Drop
  • Real-Time Progress Indicators
  • Custom Upload Restrictions
  • Extreme Customization

and ... 

...$verifyToken = md5('unique_salt' . $_POST['timestamp']);...

see demo

Just change $n. Since you're always setting it to "image.$ext" you will always get the same filename.

Instead, you will need to name it how you want it. Something like $userid."_".time().".".$ext, assuming the user's ID is in $userid.

You can have the file name and then you can append it with uniqid("{$filename}_"). So the output would be something like filename_4b3403665fea6 and then you can add the extension :)

Docs here: http://uk.php.net/manual/en/function.uniqid.php

EDIT: I apologise, I mis-read your question.
