I feel that the way images' licences are described is not sufficient to know how/if the images can be used for a particular purpose.

I actually like the way Kagi describes the images' licences — it is simpler, more intuitive, and prettier. But it is not sufficient to know whether I can re-use the image. Is public, for example, CC? What's the difference between share, and share commercial? I feel these distinctions need to be made clearer.
