jQuery draggable outside of browser

Currently, without using jQuery it is possible to drag an image from your browser onto your desktop (firefox, chrome, safari). I'd like to achieve the same thing using jQuery draggable. Currently, if I try dragging a 'draggable' element, the element disappears when it leaves the browser window.开发者_StackOverflow

Any ideas if this is possible, if so how?

Thanks.

Here is a similar discussion with respect to images:

Is it possible to Drag-and-Drop images between Web sites (applications)?
