Gallery and backgrounds

Every image you generate and every image you upload collects in the gallery.

Left, the pile: everything you generate and everything you upload lands on it. Right, one sheet off that pile, sitting behind the interface. The pane in front is drawn solid so you can see what a background is, which is the sheet underneath.

Where one goes next

From the gallery, an image can go two ways.

As a background: Pick one and it sits behind your interface.
As a download: Or download it.
