Aren't there then pictures that can tell fewer words, and some that can tell more? For instance, a picture of a solid color won't tell you much. But, a densely-packed picture could tell a lot.

And, what of the reliability of the words that a picture tells? That is, will some pictures always tell the same tale to most people, and others will tell widely different tales to everyone who sees it?

And, how would we add the fourth dimension: time? Would a set of different pictures depicting a series of events but combined into one picture count as a "picture" in the context of a picture being used to tell words? In case not, would a picture depicting a series of events in one frame - such as with arrows depicting motions or numbers indicating steps - be valid? What of holograms? Are they pictures as well, or would they be considered something else?

Discuss.
