Introducting the Awesome Uploader!
Ext JS Component

This uses native drag and drop abilities in Firefox 3.6+ & Chrome 5+ to perform uploads and show upload progress.

Also if you have flash, swfupload will be used to allow multiple file selection and upload progress.

If you do not have flash, a normal file uploader will be used.

There is also a PHP examples for how to handle the uploads.
