You'll need some AJAX progress bar (hint: google for this term ;-) that will
be getting updates from the server or request an update every second or so.

The question is if your upload code can provide progress tracking? If it's
just a call to some xyz.upload("/here/is/my-500M-file.bin") that only
returns after several minutes of uploading without giving you any updates on
how fast things go you're probably out of luck.
OTOH if it can do e.g.callbacks for progress reporting or if it can run in a
separate thread that you could query somehow you can hook that to that AJAX
thing of your choice.
