Processing images in client-side before uploading it to a server

In some cases it's necessary to process images in the client-side before uploading it to a server. This is very common in cases the user should adjust an image for some reason before submitting it.

The example below allows some basic processing in the client-side. Clicking on "SEND TO SERVER", the image is posted, an URL with the server version is returned and displayed in the right panel.
