A thorough guide to understanding color in Netscape. Learning how to optimize your graphics for the web is as much an art as it is a science. It is imperative that your graphics load quickly. My way of telling if a page is too slow is to see if I can hold my breath for the time it takes a page to load. If it takes longer than I can hold my breath it is too slow.
Images can also be something called image maps .
My favorite tool for creating image maps is imagemapper . Basically imagemaps allow you to assign different URLs to different regions of an image. This allows you to create clickable navigation bars and splash screens. The three types are NCSA, CERN and client side. NCSA and CERN are what are called server side maps requiring the browser to send a query to the server before anything happens in your browser.
