Adding an image to a plane as a reference I am modelling a mountain on the Moon using a reference photo from above. I have added a simple plane in top ortho view, and would really like to just plop that photo onto the plane. 

I started looking into UV mapping, but it doesn't seem to be what I need, at least not the way it is usually used. I added the image as a reference, which helps a little, but of course as soon as I'm not in top ortho view, it disappears. 

How would I do this?
You can use the addon Import Images as Planes, after installation go to File > Import > Images as Planes, and now you should choose the photo. It will be imported as plane. With out need of you Unwrapping it.
