This is the first Upload script I have seen that is threaded. Now I can use it for more than one area of my site without having to reinstall it in multiple locations. All their scripts seem to allow this. These guys are great!
Adding icons that represent each upload is real sweet. For example, I uploaded an Excel file that contains our contact list and I was able to show an Excel icon so my users knew what file type it was. File size is also shown.
Very nice script!
