lost background image

I was modeling along a background image and I think I might have pushed a key but my background image disappeared. So I tried getting it back but I cant. What happened?:frowning:

Background image will only show in top, side, or front views (Numpad 1,3,7), or Camera view (Numpad 0). Also you need to be in orthographic view, not perspective (Numpad 5 to toggle).

It was the orthographic view.
