You may also need to increase the max memory per PHP instance.

Umm... at least with PHP2 those are only defined if the non-default 
option to register globals is enabled. Otherwise its 
$_FILES['http_variable_name']['size'], ['name'], ['tmp_name'], ['type']

There's a handy PHP function that auto-moves temp files to a location of 
your chosing, and does some basic checking too. The function is called 
"move_uploaded_file".

Anyway I've also sent you a script, a bit of a different approach. Hope 
its of some use, though it could be commented better...
