Hi,

You cannot do a lot of scripting against a file-upload formelement in
Javascript.
This is intentionally because if scripting was possible, you would be able
to add more files (for example: all kind of systemfiles), and create a
serious securityproblem.

I think the easiest solution for you is using CSS:
1) Place the fileuploadpart in a div that has display:none
2) Once the checkbox is checked, you change this to display=block.

Please note that people who have JS disabled will be left out with the
described solution, because they have no way of making the div visible
again.
