(Note: The change caused by this menu option is only 
visible by opening another hypertext file or by using 
a jump link to another file.)

The "Disable Images" menu option sets a flag
which is used by the OnAssertMatchFound 
method of the THyperTextParser component. 
This method is used to override processing of 
matches against the currently active regular 
expression. In this case, any match against
a standalone image has its text replaced by
the phrase "inline image". (This could be
used by a text-only HTML viewer, for example.) 

(Note: Assert methods normally are used to abort
all further processing of an action, while the
Handle Methods modify the processing. These
two methods can each be overridden in code by
direct assignment for Assert types and virtual
overriding for Handle types.)
