if ($uploaded_size > 350000)Assuming that you didn't change the form field in our HTML form (so it is still named uploaded), this will check to see the size of the file. If the file is larger than 350k, they are given a file too large error, and we set $ok to equal 0.
{
echo "Your file is too large.<br>";
$ok=0;
}
You can change this line to be a larger or smaller size if you wish by changing 350000 to a different number. Or if you don't care about file size, just leave these lines out.
