I have dispensed with all images that used to be on each page. There weren’t that many, but they didn’t add much value to the site. The page loads faster now, and the function of the images have been replaced by text. I realize that the images would have been cached in the browser after the first page, but that first time would be slower than it is now, and I prefer to give a zippy first impression. Another benefit is I get to do cool things with style sheets to replace the images.
