You can use Java script to detect the resolution setting of some ones computer screen, I don't know exactly how to do it but I know that you can do it in flash, Its called a shared object, you can find out more about it if you use a search engine. A good book to use would be Dreamweaver Demystified, Using dreamweaver allows you to write JavaScript through a wizard, Coffee Cup html editor is a good program too, and another good book to reference is HTML for dummies I learnde alot from it because when I started out in web design I was and maybe still am a dummy LOL. Shared objects are great because it will automatically resize the page to match the users computer setting and it can even detect things like what Operating System they are using and whether or not they have the flash plugin or whatever player you they are have and it will execute different commands based on the retrieved data.
