Drag images into your email messages using Gmail

I read this morning that Google added the ‘drag-n-drop’ feature to image attachments to mail.  Which is pretty exciting because if you think about it, you are really dragging an image INTO a browser.  I’m really curious what type of Javascript handling you need behind the scenes in order to ‘capture’ the image / attachment and upload it / display it in the message inline, then send it forward.  Doesn’t seem like an easy task, unless Chrome (Browser) has some plugin/code specifically for this purpose.
