In this tutorial, I’m going to look at the GIF and JPEG Optimizer commands, and show how you can use them to make good-looking, fast-loading Web graphics. (Paint Shop Pro 7 also features the PNG Optimizer, which I may cover in a later tutorial.)
As of version 5 and greater, Photoshop includes a very handy “Save for Web” command. This feature allows you to produce a copy of your image that is optimised for Web use. This means that the image file will be as small as possible, and that the image will use only Web-safe colours (if desired). Save for Web can produce GIF, JPEG, or PNG format images.
