file uploader class issues

Yea ok. I don't think your following. It has nothing to do with cross browser problems.

Validating the MIME type of documents for security reasons is not a secure way to check the files that have been uploaded. With a perl script you can send the correct MIME type for a image/gif, then some binary data, then a phpinfo(), then some more binary data.

The best/easiest/secure way to do file uploads is do a file extension check and upload to a folder/subdomain where with a .htaccess and the following.

Code:

RemoveType application/x-httpd-php php
AddType text/html php

or something similar. this may not work for php running as cgi.
