img.src = e.target.result;

Dude, the "src" attribute of an image is a URL, not a string where every character is an int between 0 and 255 !!

You have to use ReadAsArrayBuffer() instead, and then the canvas API to render the ArrayBuffer you have into the context of a canvas.

Edit: If you don't want to show it in an image, but just to Ajax it to your server, here is a solution !
