Hi DFWBob and welcome to our community
The books are simple images. You should be able to easily
change them using your WebHelp skins editor.
The TOC, Search, Index and Glossary tabs can be turned on or
off by expanding the Single Source Layouts pseudo folder and
double-clicking the WebHelp layout. When you step through the
ensuing dialogs, you will see many options. You may even reorder
them via the dialogs.
Hope this helps... Rick
