This site tries to maintain a good balance between high color, attractive graphics and fast, simple page design. Some Internet Service Providers, such as AOL and CompuServe, will compress and cache graphics.
Compression reduces the size of graphics.
Caching stores them on your hard drive. This conserves your provider's server capacity and improves your Internet session. The bad news is it can also reduce the number of colors in graphics and make them look blotchy. Unfortunately, there is often no way to completely fix this on your computer. One thing you can control is graphic compression.
