Upload and crop image before sending it to the server [closed]

Is there some client components (jquery/swf) that will give the possibility to upload and crop (user should be able to select the area to crop) an image in the browser and then send the cropped image to the server?

I'm on asp.net-mvc (not sure if it matters)

What happens to the image area after cropping is completed?

By default, after you crop a picture, the cropped areas remain part of the file, hidden from view. However, you can reduce file size by removing the cropped areas from the picture file.

jcrop

Jcrop is the quick and easy way to add image cropping functionality to your web application. It combines the ease-of-use of a typical jQuery plugin with a powerful cross-platform DHTML cropping engine that is faithful to familiar desktop graphics applications.
