Some images in Group Explorer's help system are auto-generated by Group Explorer every time the page is loaded. Because the help pages you are currently viewing are being displayed by your web browser (which is not Group Explorer, and cannot create, for instance, a multiplication table), such images are not currently viewable.
If you would like to see those images, you will need to view Group Explorer's help from within Group Explorer itself, where it was primarily designed to be viewed. This web version is provided as an extra convenience, but is not the originally intended medium.
