There's no number built into the law, and in the various case rulings
it is determined in a very arbitrary way. We purposely avoid specific
numbers (i.e. "no more than 3 per page" or "no more than 400 pixels
wide") because it would just provide a false sense of accuracy and
specificity. It has to come down to good judgment in the end -- it is
easier to say what is definitely not fair use than it is to say what
definitely is.
