Review Ender's Realm Graphics is an excellent repository of graphics for World Wide Web pages. Everything you need to spruce up your WWW page, from those little smiley-face icons to fancy lines dividing paragraphs is here. In an age in which everybody needs a World Wide Web page to show off their library to the rest of the world, text-only Web pages, while functional, don't grab peoples attention.
Graphics are the way to go.
But not everyone has access to a nifty graphics program like Photoshop. Ender's Realm is a good starting point for finding nifty images. The site is well-organized into sections for bullets, buttons, lines, and icons. Tables are heavily used for the layout of the sample images. I would look at this page with a graphical browser, such as Netscape or Mosaic.
