File uploader using AJAX "Uber Uploader"

It progressively displays the progress of uploading files with the progress bar. After uploading, the result is displayed with AJAX without making screen transition. It is a "Uber Uploader" that is being developed with open source that helps to do that.

If you experience the actual demo you can understand what you can do.
