In regards to Q3, they are automatically generated by the compiler Q3Map2, stored in the BSP file, and are subtractively filtered over the base texture.

A Lightimage (shader related) is a simple texture. It's average color is used to generate the color of the light emitted by the shader surface.

Re: question: light map
Awesome demo shots to explain the effect of a lightmap... neat.
Re: question: light map
It's also possible to view vertex-light only with: "r_vertexlight 1; r_fullbright 1; vid_restart"
