I seriously need help uploading files in CI using jQuery AJAX!

NO, I'm absolute not kiddin', why would you think that!? I'm still here in the forums asking this question, because it's simply not possible (as far as I've tested) to implement ANY of the solutions the way i want: in a two div setup where I constantly load views into ONE SINGLE DIV ON THE RIGHT.

I HAVE made it post as a 'normal' form. But that's not what I'm asking.

So I need to post a form from one view loaded into a div, and get feedback back into that view from the server (in my case to create a thumbnail from the newly uploaded image). I've spent days now trying to figure this out. And still no luck, no matter how much info you've provided.
