You may take different pictures for on-screen viewing
The small images you usually get on the computer screen mean a combination of head and shoulders shots as well as small groups.

The computer screen is different than good photo paper. It does not have the resolution to show details, and you may not be able to make up for that by making the pictures real big because the viewer may have a small (640x480 or 800x600) screen or a modem connection and not want large image files.

One way to get the same effect as looking at a detailed, high resolution paper photo is to have more than one view of the same subject. Overview pictures to set context together with close-ups of no more than 2 or three people seems to work well.

For individuals, you may find that you need to show at least one of the traditional "head and shoulders" frontal pictures.
