Regarding:

1. External links.

Technically, JavaHelp will display any external URL
(as long as you have a connection). However, keep in
mind that most modern sites employ some form of
scripting (e.g., JavaScript), and that JavaHelp does
not support scripting. Thus, JavaHelp will poorly
render many external sites.

2. Image maps.

As of JH1.1.3/JDK1.4x, image maps do work, however,
the mouse pointer does not change to indicate that the
image is "clickabke." This is a usability problem. I
don't know if it has been fixed in a more recent
version of JH and/or JDK.

This was definitely fixed. I think in JDK 1.4.1.
