Cancel button on 'Download preview images' message box

Any chance of getting a 'Cancel' button on the message box displayed wihle downloading posters?

There are many times where the 1st of the 10 preview images is the one I want, or, when it can't get the right images and it starts getting random ones, and I'm often forced to wait an extra 60-90 sec (depending on source site latency) while it slowly downloads all the preview images.

I agree that this would be a useful thing, i'll put it on the list.
