how to resize an image so it shows in its entirety within an object? lets take a 3d rectangle add a image to only one side of it, after unwrapping it. Using nodes, adding an image that will show bigger then that objects face. the image appears on the selected face of the object, but it is way too big to show the entire image on the selected face. How do I go about resizing the image so it shows one image within the selected face of the object?

UV Unwrapping

The best thing to do would be to start with a blank cube, then select only the face that you want to have the car. Key Numpad 5 to enter Orthographic View, and then key either Numpad 1, Numpad 3, Numpad 7, Ctrl + Numpad 1, Ctrl + Numpad 3, or Ctrl + Numpad 7 (whichever makes you face the selected face). Key U and select Project from View (Bounds).
