How do i get a texture to show up in rendered mode?

Do you think this is a good picture to use for a texture? should I create my own image of the police car myself or is this texture good to use in a game? what would you do?


If using cycles render add the texture node (with the correct texture selected) to input of the appropriate material shader node.
If using blender render add the texture slot to the selected material, select the correct texture and set it to influence the material color
