Meaning: an image can say something better than can words. Mentions.
Rewrite 1: the picture told me more than a book could describe
Rewrite 2: a single picture can say more than a dozen essays
Rewrite 3: I could write an essay, but printing a picture is quicker
Rewrite 4: better you should draw a map than tell him directions

Comment: These don’t as easily fit into a metaphor, but they express the same idea.
