This frame is used as an index to each set of pictures and contains buttons like this one:

Clicking each button will scroll the picture frame (above) and text frame (right) to the appropriate location.

The sub-frame above always contains a link back to the main index so that each town or village is never more than two mouse clicks away.

The text window (right) may also contain hyperlinks which will scroll the picture window to a particular location, but this window should be considered as the main index for each town or village.
