问题
I am searching for a solution that will allow a user to upload an image, crop the image, and then send the updated image to the server.
Basically, I would like to handle all the editing client side and only send the new, smaller, thumbnail to the server.
How can I do this? I have seen this is possible with Flash, but I am looking for alternative solutions.

Are you restricted to certain browsers? Using HTML5, here is a proof of concept from Anand Venkataraman. Demo is here.
