Keep in mind that users shouldn't have to wait for the entire page to
load before seeing some content. Some tips for making this happen:
- make sure you aren't just using images for content and give the users
enough text to read while images are loading
- include good alt text [1] for your images so the user has an idea of
what they will see once each image loads
- set the width and height of all images so the browser can calculate
the page layout before the images load
- order the page content/markup in logical order (e.g. content before
navigation), and use CSS to position it on the page (e.g. navigation on
the left, content on the right); this will make the browser start
loading the most important content first (someone correct me if I'm
wrong about this)
