jQuery HTML5 Uploader

jQuery HTML5 Uploader is a lightweight jQuery plugin that lets you to quickly add an upload system a-la-Gmail into your web app.

You only need to create a dropbox element (i.e. a div) and jQuery HTML5 Uploader will do the rest. Then you can drag & drop one or more files on the element and the files will be uploaded.

It also works with the multiple input file element.

The upload function is divided into two asynchronous operations: client side, the file is loaded in the browser memory with a FileReader object. Useful if you want, for example, to show the image preview while uploading a picture. The server side operation consists in sending the binary file string to the postUrl (see settings).

It has been tested and works on Firefox and Chrome.
