But it's getting better!
HTML5 defines a new .files property for <input type=file> that gives
you the file's name, size (in bytes) and content-type (as the browser
would send it on the wire in the multipart/form-data).
This is already implemented in Chrome 5 (beta and dev channels) and
Firefox 3.0+

And there's the FileAPI that's already implemented in Firefox 3.6 and
gives you access to the files' *content*

Whether you can use Flash (or BrowserPlus, or HTML5, or Silverlight,
etc. [1]) or not, you should do that anyway.
