It depends on the page. The main problem is with tables. 

If the browser doesn't know how big all the images within the table are, then it cannot know how big the entire table will be. Therefore it cannot display any of the table until it has downloaded all of all the images. 

If you include the height and width attribute for all images within the table, then as soon as the browser reaches the </table> tag it can display the table with placeholder boxes, allowing the user to read the text and use navigation while the images are gradually filled in.
