If you need to include a large, detailed image, first provide readers with a smaller, thumbnail-size version, so they know whether the larger image would be worth their time. The same principle applies to multimedia elements. Give visitors the option of receiving any sizable Java applets or Shockwave movies. If part of your site is still under construction, don't create a link to it yet. Value the Web's diversity.
Surfers use a variety of computers, screen resolutions, browsers, and connection methods.
Though graphical browsers from Netscape and Microsoft get the lion's share of attention these days, many people still use text-based browsers such as Lynx. And some people who use graphical browsers disable graphics for faster surfing. So, if you use clickable images or image maps as navigational tools, make sure you also include text-based links on the same page. Also, test your pages using different browsers and screen resolutions to make sure that what looks slick with one doesn't look incoherent with another. Strive for consistency and creativity.
