What makes some sites so slow to load?

Usually, slow-loading sites are full of large, poorly conceived graphics. A screen full of text will generally require only a few K bytes of storage. It will download to a user's screen almost as fast as they can click to request it. A full-screen graphic, on the other hand, will probably require a file of 300K to 500K in size. Downloading such a file with a 56K modem takes so long that most users will just give up and click off to somebody else's page before the beautiful picture ever flashes into life on their screen. Get the picture? Keep graphics sized reasonably for the Web, and make sure your Web designer understands how to minimize colors and DPI settings on graphics to make graphic elements look sharp on the WWW, but not take up too much space. (HINT: We know how to do that.)
