"Although images were present on the pages of textbooks before, there are more images now; these images look and function differently from those found before. The page is used differently to the way it had been"
When comparing textbooks and writing from many years ago, one can see that the way in which images and diagrams were utilized than is very different from now. Images are now used from often in print texts, and they are often used to tell more of the story than the print is.
