Background image isn't visible in the viewport Is the problem with the picture or something else?
I'm trying to put a image to Blender's viewport but its not showing. I tried pressing Ctrl and Numpad1 but it just made the default shape rounder.
I'm using blender 2.78.
Use the Numpad 1 to enter preset ortho view. Ctrl+1 from the top of your keyboard adds a Subdivision Surface modifier.
