These hours correspond to lunch hours and after hours when employees explore the Internet on their own time. The third consideration is the amount of time one can reasonably expect someone to wait for a page to load. Planning a page so that the time a visitor waits is minimal is a good strategy. Assume that a casual visitor will wait 30 seconds, and that an interested visitor will wait no more than two minutes. Each kilobyte of information takes approximately one second to download, so file sizes should be between 30k and 125k.
Images are an important part of Web page design.
These file formats compress the size of images. When creating images and graphics for a Web page, consistency of file format is essential. GIF is the universally accepted graphic file standard for the Web. The GIF format offers moderate compression capability. However, GIF images can be saved with a color palette of 2 to 256 colors, allowing the designer to limit the number of colors.
