I had an AJAX file upload solution built out, where you use javascript
to create a hidden iframe element, then you set the form to post to
that hidden frame. It worked, however if you go through the trouble of
that i would recommend you opt for a flash based file uploader. Much
more robust and can give you a multiple file upload functionality.
