Please close full screen picture preview if I click on an empty area

[bkil]

If I click on an image attachment to view it full screen without the eye sore of #1102, I can only close the preview by clicking the small X on the top right of the screen, usually very distant from the picture itself and from where I opened the image from.

Most other software support closing such previews by either clicking anywhere (if it doesn't support zooming on click), or by clicking anywhere outside the preview (usually on the shaded area or on any visible controls).
