Is it possible to pop open the upload file dialog without requiring the user to press Browse?
<p>I think I've seen Gmail do it in Chrome or Internet Explorer, but I've never seen it in Firefox. I thought I'd ask anyways. Is it possible to do a file upload without requiring an <code>&lt;input type="file" /&gt;</code>? I see that you can <a href="http://stackoverflow.com/questions/543926/is-it-possible-to-ajax-a-file-upload">use iframes to automatically submit the file input</a>, so my question is </p>

<p>Can you programmatically pop up a file upload dialog?</p>

<p>If so, what browsers is it supported on?</p>
