you can optimize your images for the web. Your images should be in either .gif or .jpg formats (.gif works best for logos and navigation buttons, while .jpg works best for photographs.) The idea is to reduce the size of your graphics so that they take as few bytes as possible while retaining acceptable quality. This can be done using free on-line image optimization tools. One of the best ones out there is Gifbot, by Netmechanic (http://www.netmechanic.com/GIFBot/optimize-graphic.htm ). They have a user-friendly web-based interface that works like this: you upload your picture, they process it, and almost instantaneously they will give you several lighter versions of your graphic for you to chose. Pick the image that takes the fewest bytes while still retaining and acceptable quality level. It is not uncommon to reduce the weight of a picture by up to 70% with no noticeable decrease in quality (especially if the image is in .jpg format.)
