upload failures on large files

I'm having some problems having implemented your script,
I am unable to get file uploads of around 10mb to complete.
At the moment I get a 10053 - Connection aborted
but I'm not sure if this is due to the script timing out.

any clues?

If you look into the config.asp file you will see a "Server.ScriptTimeout = 300".  If you modify this to a higher number, the script may complete.  

Joe,
As Brian has already said, increase the timeout value and let me know the result.
