If you apply an image to a flat surface, there is no need to UV map it.

It can look as this:
box{0,1 pigment{image_map{jpg "grey.jpg"}} finish{diffuse 0.7} 
scale<800, 600, 1>}

This will apply the image "grey.jpg" to a small box then enlarge it to 
800 by 600 by 1 units block.
You can now rotate and move the box as you want, the image will follow 
it exactly.

UV maping is usefull to apply an image based pigment to some objects 
like a mesh, not all of them.
If your image is a single colour, then it's beter to simply use a simple 
pigment of the appropriate colour.

Your inut image is flat and don't contain any 3D information, looking at 
it from different locations will be similar to looking at a printed 
version from an angle.

POV-Ray works with 3D informations provided by a text file using a Scene 
Description Language, or SDL.
That is used to literaly construct your scene.
Once the scene is constructed, you can place the camera anywhere in or 
around it, and change your point of view. You also need to provide some 
illumination using one or several light_source.

There are some modelers available to help you construct your scenes. 
Take a look at the POV-Ray site, it provide links from where you can get 
some.
