How to use a texture as a 3d object?

I saw people taking textures and then making them 3d objects which can be seen in scene view, rather than just in the game view. How do I do this, how do I make them objects?

If you look rigth below the Scene tab you will see a pull down that sets the render type in the scene view.

You want to set it to textured to see textures.
