I was talking about the *saved JPEG*. 1 layer. When I right-click and "Get Info" on the file, it says the JPEG is 96K. When I *open the JPEG* in Photoshop, it's back up to 399KB. I sense an epiphany coming up for myself. This is only fleetingly related to CSS in that CSS can dramatically reduce the page size. So can optimized images. Other than that, Pfffttt. I wonder how long this conversation will continue before a list-parent steps in? Back to work. I have a bugger of a web site to finish designing and then build. It will certainly stretch my CSS skills, and get me better versed in positioning.
