It boils down to "Don't use XHR. Do use Flash or iframes". There are libraries that will do the heavy lifting for you.
Just use jQuery ajax upload plugin http://valums.com/ajax-upload/. It is actually not ajax, it's invisible iframe, but result is almost same.
For server-side you can use php with gd-library and some simple MySQL queries.
